4tronix Picon Zero v1.3 - Intelligent Robotics Controller for Raspberry Pi
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:

Pimoroni Pimoroni Automation HAT
Take control of and monitor your world with our ultimate jack-of-all-trades Raspberry Pi HAT!We've pulled together a great set of features into this home monitoring and automation controller. With relays, analog channels, powered outputs, and buffered inputs (all 24 V tolerant) you can now hook up a plethora of goodies to your Raspberry Pi all at once.Better still each channel has an indicator LEDs which means at a glance you can see what's happening with your setup. Even the analog channels have dimming LEDs that allow you to see the value they are currently sensing – swish!Ideal for smart home and automation projects, giving your greenhouse intelligent sprinklers, or scheduling your fish feeding!Features 3x 24 V @ 2 A relays (NC and NO terminals) 3x 12-bit ADC @ 0-24 V (±2% accuracy) 3x 24 V tolerant buffered inputs 3x 24 V tolerant sinking outputs 15x channel indicator LEDs 1x 12-bit ADC @ 0-3.3 V 3.5 mm screw terminals Power, Comms, and Warn! 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!

Arduino Arduino Pro Portenta H7 Lite
Portenta H7 Lite allows you to build your next smart project. Ever wanted an automated house? Or a smart garden? Well, now it’s easy with the Arduino IoT Cloud compatible boards. It means: you can connect devices, visualize data, control and share your projects from anywhere in the world. The Portenta H7 Lite is very similar to the Portenta H7, that simultaneously can run high level code along with real time tasks thanks to its two processors. It is, for example, possible to execute Arduino compiled code along with MicroPython one and have both cores to communicate with one another. However, the H7 Lite is a low-cost board with H7 functionalities that can be configured to specific use cases. Features Dual Core – Two best-in-class processors in one, running parallel tasks AI on the edge – So powerful it can run AI state machines Customization – The board is highly customizable in volumes High-level programming language support (Micropython) The Portenta H7 Lite offers twofold functionality: it can run either like any other embedded microcontroller board, or as the main processor of an embedded computer. For example, use the Portenta Vision Shield to transform your H7 Lite into an industrial camera capable of performing real-time machine learning algorithms on live video feeds. As the H7 Lite can easily run processes created with TensorFlow Lite, you could have one of the cores computing a computer vision algorithm on the fly, while the other carries out low-level operations like controlling a motor or acting as a user interface. Solutions High-end industrial machinery Laboratory equipment Computer vision PLCs Robotics controllers Mission-critical devices High-speed booting computation (ms) Two Parallel Cores The Portenta H7 Lite’s main processor is the STM32H747 dual core including a Cortex-M7 running at 480 MHz and a Cortex-M4 running at 240 MHz. The two cores communicate via a Remote Procedure Call mechanism that allows calling functions on the other processor seamlessly. Both processors share all the in-chip peripherals and can run: Arduino sketches on top of the ARM Mbed OS Native Mbed applications MicroPython / JavaScript via an interpreter TensorFlow Lite A New Standard for Pinouts The Portenta family adds two 80-pin high-density connectors at the bottom of the board. This ensures scalability for a wide range of applications: simply upgrade your Portenta board to the one suiting your needs. USB-C Multipurpose Connector The board’s programming connector is a USB-C port that can also be used to power the board, as a USB Hub, or to deliver power to OTG connected devices. Arduino IoT Cloud Use your Portenta board on Arduino’s IoT Cloud, a simple and fast way to ensure secure communication for all of your connected Things.
