Raspberry Pi HATs

Display HAT Mini features a bright 18-bit capable 320x240 pixel display with vibrant colours and formidable IPS viewing angles, connected via SPI. It's got four tactile buttons for interacting with your Raspberry Pi with your digits and a RGB LED for notifications. A QwST connector (Qwiic / STEMMA QT) and a Breakout Garden header is also squeezed in so it's a doddle to connect up different kinds of breakouts. It will work with any model of Raspberry Pi with a 40 pin header, but we think it goes with the Raspberry Pi Zero particularly well - we've included a pair of standoffs so you can use to bolt HAT and Raspberry Pi together to make a sturdy little unit. To accommodate the screen Display HAT Mini is a bit bigger than a standard mini HAT or pHAT – it's around 5 mm taller than a Raspberry Pi Zero (so a Mini HAT XL or a Mini HAT Pro, if you will). Display HAT Mini lets you turn a Raspberry Pi into a convenient IoT control panel, a tiny photo frame, digital art display or gif-box, or a desktop display for news headlines, tweets, or other info from online APIs. This screen is a handy 3:2 ratio, useful for retro gaming purposes! Features 2.0” 320x240 pixel IPS LCD screen, connected via SPI (~220 PPI, 65K colours) 4x tactile buttons RGB LED Qw/ST (Qwiic/STEMMA QT) connector Breakout Garden / I²C header Pre-soldered socket header for attaching to Raspberry Pi Compatible with all models of Raspberry Pi with a 40-pin header.

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.

LED indicators SPI, TX (#14), RX (#15), #25 pins broken out Automation HAT pinout Compatible with all 40-pin header Raspberry Pi models Python library Schematic Comes fully assembled (broken out pins require soldering) SoftwareAs ever, we've made a super-simple to use Python library to take advantage of Automation HAT's multitudinous functions, with examples to get you started.Our input, output and relay examples show you how to read the analog and digital inputs, switch the outputs on and off, and control the relays.Notes We recommend you use a set of brass M2.5 standoffs with Automation HAT to avoid pins contacting the HDMI port if the HAT is pushed down Loads for the buffered outputs should be switched on the ground side, i.e. 12/24 V (from supply) -> load -> output terminal -> ground (from supply) The relays can tolerate up to 2 A each and should be switched on the high side The sinking outputs can sink a maximum 500 mA total across the 3 outputs, so if you use a single channel you can sink the whole 500 mA across it. The accuracy of the ADC is ±2%. Do not use to switch mains voltages!
