Click here to learn how to update the Raspberry Pi kernel Using microphones with the DAC+ ADC The DAC+ ADC is equipped with a stereo analogue input that can be configured for a wide range of input voltages. It performs best with line-level analogue sources. However, it is also possible to use it as a microphone input. You can only use dynamic microphones. Microphones that require a power supply are not supported. The microphone output voltage is very low. This means you need to amplify it. The DAC+ ADC has the necessary pre-amplifier already equipped. You will have to set the jumpers correctly. The sound from the input won’t be played back automatically on the output. You will have to use some software that reads the input and outputs it again. Setting the correct input amplifier settings for a microphone By default, the input sensitivity is matched for line-level audio sources. This is done via a jumper on the J1 header. In order to use a microphone, the jumper needs to be set up as shown below. Audio input to output There is no direct connection between the input and the output. That leads to the input from the connected microphone to not be played back automatically. If you want to hear it on the output, you need to use the command line tool alsaloop can be used for this.

Witty Pi is an add-on board that adds realtime clock and power management to your Raspberry Pi. It can define your Raspberry Pi’s ON/OFF sequence, and significantly reduce the energy usage. Witty Pi 4 is the fourth generation of Witty Pi and it has these hardware resources onboard: Factory calibrated and temperature compensated realtime clock with ±2 ppm accuracy. Dedicated temperature sensor with 0.125 °C resolution. On-board DC/DC converter that accepts up to 30 V DC. AVR 8-bit microcontroller (MCU) with 8 KB programmable flash. Accurate realtime clock and ON/OFF scheduling The realtime clock (RTC) on Witty Pi 4 has been calibrated in the factory and Witty Pi 4’s firmware also makes temperature compensation for the crystal. This makes the RTC very accurate and the actual annual error is limited within ±2 ppm. When your Raspberry Pi boots up, the time stored in the RTC will overwrite the system time. As a result, your Raspberry Pi knows the correct time even without accessing the Internet. You can schedule the startup and/or shutdown of your Raspberry Pi, and make it a time-controlled device. You can even define a schedule script to schedule complicated ON/OFF sequence for your Raspberry Pi. Scheduling the ON/OFF sequence for Raspberry Pi is the most popular feature of Witty Pi, and it is extremely useful for systems that powered by battery. By only turning on Raspberry Pi when necessary, the battery can be used way much longer with Witty Pi installed. Temperature-controlled device The temperature sensor on Witty Pi 4 has 0.125 °C resolution. The temperature data is used for compensating the crystal and make the RTC more accurate. You can also specific the action (startup or shutdown) when temperature goes above or below the preset threshold. Which means you can also make your Raspberry Pi a temperature-controlled device. DC/DC converter and e-latching power switch Witty Pi 4 comes with a DC/DC converter on board, which allows you to power your device with 6~30V power supply. You can also power your device with 5 V via the USB type C connector. Witty Pi 4 also implements an e-Latching power switch, which is very similar to the power switch on your PC/Laptop computer. You can gracefully turn on/off your Raspberry Pi with a single tap on the button. The software running in background will execute the shutdown command before the power gets cut, this avoid the data corruption caused by hard shutdown. Witty Pi 4 supports all Raspberry Pi models that has the 40-pin GPIO header, including A+, B+, 2B, Zero, Zero W, Zero 2 W, 3B, 3B+, 3A+ and 4B. You will need to solder the 40-pin header to Zero/Zero W/Zero 2 W model beforehand, so they can make reliable connection with Witty Pi. Single I²C device Witty Pi 4 uses MCU to emulate a single I²C device with default address 0x08, and also map all I²C registers in realtime clock and temperature sensor as virtual I²C registers in the same device. You can access all I²C registers in realtime clock and temperature sensor via the single I²C device emulated by Witty Pi 4. The advantage of this new design is that Witty Pi 4 hides other I²C devices (realtime clock, temperature sensor) and becomes the proxy of them to talk to Raspberry Pi. Because the I²C address used by Witty Pi 4 can be changed to any value, you can always avoid the I²C address conflicting. UWI support Witty Pi 4 is fully supported by UWI (UUGear Web Interface), and you can access you Witty Pi 4 on any device that have network access.

The Picon Zero is an add-on for the Raspberry Pi. It has the same size as a Raspberry Pi Zero, making it ideal to function as a pHat. Of course, it can be used on any other Raspberry Pi via a 40-pin GPIO connector.As well as two full H-Bridge motor drivers, the Picon Zero has several Input/Output pins giving you multiple configuration options. That allows you to easily add outputs or analog inputs to your Raspberry Pi without any complicated software or kernel-specific drivers. At the same time, it opens up 5 GPIO pins from the Raspberry Pi, and it provides the interface for an HC-SR04 ultrasonic distance sensor.The Picon Zero comes with all components, including the headers and screw terminals, fully soldered. Soldering isn't required. You can use it right out of the box.Features pHat format PCB: 65 mm x 30 mm Two full H-Bridge motor drivers. Drive up to 1.5 A continuously per channel, at 3 V - 11 V. Each motor output has both a 2-pin male header and a 2-pin screw terminal. The motors can be powered from the Picon Zero's 5 V or an external power source (3 V - 11 V). The Picon Zero's 5 V can be selected to be from the Raspberry Pi's 5 V line, or a USB connector on the Picon Zero. That means that you can effectively have 2 USB battery banks: one to power the servos and motors on the Picon Zero and the other to power the Pi. 4 Inputs that can accept up to 5 V. These inputs can be configured as follows: Digital inputs Analog inputs DS18B20 DHT11 6 Outputs that can drive 5 V and be configured as: Digital Output PWM Output Servo NeoPixel WS2812 All Inputs and Outputs use GVS 3-pin male headers. 4-pin female header that connects directly to an HC-SR04 ultrasonic distance sensor. 8-pin female header for Ground, 3.3 V, 5 V, and 5 GPIO signals allowing you to add their additional features. Hardware ConfigurationPicon Zero has two jumpers for setting the hardware configuration. Ensure that you have placed them in the correct position. JP1 – Board 5 V Selector. This jumper selects where to get the 5 V power from for the Picon Zero Outputs. The options are: Jumper at the top between RPI and 5 V. The 5 V power for the board is taken from the Raspberry Pi pins on the GPIO connector. Because of the low power output devices and the 5 V motors, all devices can be powered with a single 5 V power input. Jumper at the bottom between USB and 5 V. The 5 V power is taken from the microUSB connector on the Picon Zero. Useful for higher power output devices, since you can provide extra power through the micro-USB connector on the board JP2 – Motor Power Selector. This jumper selects where the motors get the power. The two options here are the following: Jumper at the top between MotorPower and Vin. The motors are driven via the 2-pin screw terminal. The voltage can be between 3 V and 11 V. Useful for motors that require a voltage different from 5 V, or that require more current than is available on either of the USB input connectors Jumper at the bottom between 5 V and MotorPower. The motors are driven from the board's 5 V. Raspberry Pi ConfigurationThe Picon Zero is an I²C device. Make sure your Raspberry Pi is set up correctly to use I²C and SMBus: sudo apt-get install python-smbus python3-smbus python-dev python3-dev sudo nano /boot/config.txt Add the following lines at the end of the file dtparam=i2c1=on dtparam=i2c_arm=on Press Ctrl-X and use the default prompts to save sudo reboot Plugin the Picon Zero onto the Pi and run i2cdetect -y 1If everything goes well, you will see the Picon Zero showing up as address 22 as shown below:

The Home Automation HAT uses only pluggable connectors. In addition, the latest release (V4.0 and up) has two new communication ports: 1-Wire and RS485. The card uses only 5 V power. On-board step-up power supply generates 12 V to power the 0-10 V analog outputs. A general purpose push-button, wired directly to a Raspberry Pi GPIO pin, can be used to shut down Raspberry Pi without a keyboard, or to force any output to a desired state. Ideal solution for your Raspberry Pi Home Automation projects. Read temperatures in up to 8 zones with analog inputs. Control your heating and cooling system with the 8 onboard relays. Use the 8 optically isolated digital inputs for your security system. Activate the hardware watchdog to monitor and power cycle the Raspberry Pi in case of software lockup. Control four-light systems with the four PWM open-drain outputs (you supply external power up to 24 V). Control four light dimmers using 0-10 V outputs. Compatibility The card is compatible with all Raspberry Pi versions from Zero to 4. It shares the I²C bus using only two of the Raspberry Pi’s GPIO pins to manage all eight cards. This feature leaves the remaining 24 GPIOs available for the user. Power Requirements The Home Automation card needs 5 V to operate and can be powered from Raspberry Pi or from its own pluggable connector. The onboard relay coils are also powered from the 5 V. An on-board 5V to 12V step-up power supply generates the voltage to drive the 0-10 V analog outputs. A local 3.3 V regulator powers the rest of the circuitry. The card needs 50 mA to operate with all relays off. Each relay needs up to 80 mA to turn on. Relays The 8 on-board relays have contacts brought out to heavy duty pluggable connectors, which make the card easy to use when multiple cards are stacked up. Relays are grouped in two sections of four relays each, with one common terminal and one N-O contact for each relay. Relays are rated 10 A/24 VDC and 250 VAC, but due to the board geometry limitation, the relays can switch only 3 A and 24 V, AC or DC. Status LEDs show when RELAYS are ON or OFF. Stacking Multiple Cards Up to eight Home Automation cards can be stacked on your Raspberry Pi. Each card is identified by jumpers you install to indicate the level in the stack. Cards can be installed in any order. The three position jumper on the upper right corner of the card selects the stack level. Features Eight relays with status LEDs and and N.O contacts Eight layer stackable Eight 12-bit A/D inputs, 250 Hz sample rate Four 13-bit DAC outputs (0-10 V dimmers) Four PWM 24 V/4 A open-drain outputs Eight optically isolated digital inputs Contact closure/Event counters up to 500 Hz Four Quadrature Encoder inputs 26 GPIOs from Raspberry Pi available 1-WIRE and RS485 communication ports Pluggable Connectors 26-16 AWG for all ports On-board hardware watchdog On-board resettable fuse Reverse power supply protection Brass stand-offs, screws and nuts included Hardware self-test with loop-back cable Open source hardware, schematics available 32-bit Processor running at 64 MHz Uses only I²C port (address 0x28..0x2f ), all GPIO pins available Specifications Power supply: Pluggable Connector, 5 V/3 A Power consumption: 50 mA (all relays off), 700 mA (all relays on) On board resettable fuse: 3 A Open Drain outputs: maximum 3 A, 24 V Relays 1,2,3,4,5,8: N-O contacts, 6 A/24 VAC or DC Relays 6,7: 3 A/24 VAC or DC Analog Inputs: Maximum input voltage: 3 V Input Impedance: 50 KΩ Resolution: 12 bits Sample rate: 250 samples/sec.

The ZED-F9R module is a 184-channel u-blox F9 engine GNSS receiver, meaning it can receive signals from the GPS, GLONASS, Galileo, and BeiDou constellations with ~0.2-meter accuracy! That's right; such accuracy can be achieved with an RTK navigation solution when used with a correction source. Note that the ZED-F9R can only operate as a rover, so you will need to connect to a base station. The module supports the concurrent reception of four GNSS systems. The combination of GNSS and integrated 3D sensor measurements on the ZED-F9R provide accurate, real-time positioning rates of up to 30Hz. Compared to other GPS modules, this pHAT maximizes position accuracy in dense cities or covered areas. Even under poor signal conditions, continuous positioning is provided in urban environments and is also available during complete signal loss (e.g. short tunnels and parking garages). The ZED-F9R is the ultimate solution for autonomous robotic applications that require accurate positioning under challenging conditions. This u-blox receiver supports a few serial protocols. By default, we chose to use the Raspberry Pi's serial UART to communicate with the module. With pre-soldered headers, no soldering is required to stack the pHAT on a Raspberry Pi, NVIDIA Jetson Nano, Google Coral, or any single-board computer with the 2x20 form factor. We have also broken out a few 0.1'-spaced pins from the u-blox receiver. A Qwiic connector is also added in case you need to connect a Qwiic enabled device. U-blox based GPS products are configurable using the popular but dense, windows program called u-centre. Plenty of different functions can be configured on the ZED-F9R: baud rates, update rates, geofencing, spoofing detection, external interrupts, SBAS/D-GPS, etc. The SparkFun ZED-F9R GPS pHAT is also equipped with an on-board rechargeable battery that provides power to the RTC on the ZED-F9R. This reduces the time-to-first fix from a cold start (~24s) to a hot start (~2s). The battery will maintain RTC and GNSS orbit data without being connected to power for plenty of time. Features 1 x Qwiic Connector Integrated U.FL connector for use with an antenna of your choice Concurrent reception of GPS, GLONASS, Galileo and BeiDou 184-Channel GNSS Receiver Receives both L1C/A and L2C bands Horizontal Position Accuracy: 0.20 m with RTK Max Navigation Rate: Up to 30Hz Time to First Fix Cold: 24 s Hot: 2 s Operational Limits Max G: ≤4 G Max Altitude: 50 km Max Velocity: 500 m/s Velocity Accuracy: 0.5 m/s Heading Accuracy: 0.2 degrees Built-In Accelerometer and Gyroscope Time Pulse Accuracy: 30ns Voltage: 5 V or 3.3 V, but all logic is 3.3 V Current: ~85mA to ~130mA (varies with constellations and tracking state) Software Configurable Geofencing Odometer Spoofing Detection External Interrupt Pin Control Low Power Mode Supports NMEA, UBX, and RTCM protocols over UART

Raspberry Pi 4 was welcomed by the Pi enthusiasts for the increased processing power. However, this came at a price. The RPi 4 can draw up to 3 Amps, which means it has to dissipate 15 W of power. Raspberry Pi cooling is a must. From the simplest passive heat sink, through elaborate fan blowers and even to an exotic water-cooled idea, many options are available.The Smart Fan has the form factor of the Raspberry Pi HAT. Its own tinny 32-bit processor receives commands from Raspberry Pi through the I²C interface. A step-up power supply converts the 5 V provided by Raspberry Pi to 12 V, ensuring precise speed control. Using pulse width modulation, it powers the fan just enough to maintain a constant temperature of the Raspberry Pi processor.The Smart Fan preserves all the GPIO pins, allowing any number of cards to be stacked on top of Raspberry Pi. If another add-on card has to dissipate power, a secondary Smart Fan can be added to the stack.DIN-Rail MountingTogether with multiple add-on cards, the Smart Fan can be installed on the DIN-Rail, for sturdy industrial applications.Stack Level JumperTwo Smart Fans can be installed on top of each Raspberry Pi. The assumption is that you have one more card in the stack which requires cooling. The bottom side of the Smart Fan has a jumper which needs to be installed on the second fan, in order for the Raspberry Pi to differentiate the two I²C addresses.Features 40 x 40 x 10 mm fan with 6 CFM airflow Step-up 12 V power supply for precise fan speed control PWM Controller modulates the fan to keep constant Pi temperature Draws less than 100 mA of power Stackable to itself, 2 fans can be added to Raspberry Pi Fully stackable allows adding other cards to Raspberry Pi Uses only I²C interface, leaves full use of all GPIO pins Super quiet and efficient Included Smart Han HAT 40 x 40 x 10 mm Fan with mounting Screws Mounting Hardware Downloads User's Guide Open Source Hardware Schematic 2D CAD Drawing Command line Python Libraries Node-Red Nodes

The servo control is based on the SparkFun servo pHAT, and thanks to its I2C capabilities, this PWM add-on saves the Raspberry Pi's GPIO pins, allowing you to use them for other purposes. We have also provided a Qwiic connector for easy interfacing with the I²C bus using the Qwiic system. Whether you use the Auto pHAT with a Raspberry Pi, NVIDIA, Jetson Nano, Google Coral, or other SBC, it makes for a unique robotics addition and board with a 2x20 GPIO. The DC motor control comes from the same 4245 PSOC and 2-channel motor ports system used on the SparkFun Qwiic Motor Driver. This provides 1.2A steady-state drive per channel (1.5A peak) and 127 levels of DC drive strength. The SparkFun Auto pHAT also supports up to two motor encoders thanks to the onboard ATTINY84A to provide more precise movement to your creation! Additionally, the Auto pHAT has an on-board ICM-20948 9DOF IMU for all your motion-sensing needs. This enables your robot to access the 3-Axis Gyroscope with four selectable ranges, 3-Axis Accelerometer, again with four selectable ranges, and 3-axis magnetometer with an FSR of ±4900µT. Power to the SparkFun Auto pHAT can be supplied through a USB-C connector or external power. This will power either the motors only or power the motors and the Raspberry Pi that is connected to the HAT. We've even added power protection circuits to the design to avoid damage to power sources. Features 4245 PSOC and 2-channel motor ports programmable using Qwiic library Onboard ATTINY84A supports up to two DC motor encoders 5V pass-through from RPi Onboard ICM-20948 9DOF IMU for motion sensing accessible via Qwiic library PWM control for up to four servos Qwiic connector for expansion to full SparkFun Qwiic ecosystem Designed for stacking, full header support & can use additional pHATs on top of it Uninhibited access to the RPi camera connector & display connector.

Add global GSM connectivity and GPS tracking to your project with a BerryGPS-GSM. This is an all in one module which can provide location tracking and GSM services such as data, text and SMS to your project. It comes in the same form factor as a Raspberry Pi Zero, which makes it nice and compact when used with a Raspberry Pi Zero. The two main components that make this board great are; uBlox CAM-M8 GPS module (Same GPS found on BerryGPS-IMU V3) uBlox SARA-U201 GSM for GSM connectivity, which has global coverage. Both of these modules working together results in obtaining a GPS fix in secs, using Assisted GPS. Typically, a GPS module can take a few minutes to get Time To First Fix(TTFF), or even longer if you are in built up areas. This is because the Almanac needs to be downloaded from satellites before a GPS fix can be acquired and only a small portion of the Almanac is sent in each GPS update. Assisted GPS speeds this up significantly by downloading ephemeris, almanac, accurate time and satellite status over the network, resulting in faster TTTF, in a few seconds. This is very similar how to GPS works on a smartphone. BerryGPS-GSM has been designed for the Raspberry Pi Zero, however it works with all versions of Raspberry Pi. We have created a USB-to-USB PCB connector to be used with a Raspberry Pi Zero, which is designed to make your project more compact.
