Cytron Maker Pi RP2040 features the first microcontroller designed by Raspberry Pi – RP2040, embedded on a robot controller board. This board comes with dual channel DC motor driver, 4 servo motor ports and 7 Grove I/O connectors, ready for your next DIY robot / motion control project. Now you can build robot, while trying out the new RP2040 chip. The DC motor driver onboard is able to control 2x brushed DC motors or 1x bipolar/unipolar stepper motor rated from 3.6 V to 6 V, providing up to 1 A current per channel continuously. The built-in Quick Test buttons and motor output LEDs allow functional test of the motor driver in a quick and convenient way, without the need of writing any code. Vmotor for both DC and servo motors depends on the input voltage supplied to the board. Maker Pi RP2040 features all the goodness of Cytron's Maker series products. It too has lots of LEDs useful for troubleshooting (& visual effects), is able to make quite some noise with the onboard piezo buzzer and comes with push buttons ready to detect your touch. There are three ways to supply power to the Maker Pi RP2040 – via USB (5 V) socket, with a single cell LiPo/Li-Ion battery or through the VIN (3.6-6 V) terminals. However only one power source is needed to power up both controller board and motors at a time. Power supply from all these power sources can all be controlled with the power on/off switch onboard. Cytron Maker Pi RP2040 is basically the Raspberry Pi Pico + Maker series' goodness + Robot controller & other useful features. Therefore this board is compatible with the existing Pico ecosystem. Software, firmware, libraries and resources that are developed for Pico should work seamlessly with Cytron Maker Pi RP2040 too. CircuitPython is preloaded on the Maker Pi RP2040 and it runs a simple demo program right out-of-the-box. Connect it to your computer via USB micro cable and turn it on, you will be greeted by a melody tune and LEDs running light. Press GP20 and GP21 push buttons to toggle the LEDs on/off, while controlling any DC and servo motors connected to it to move and stop. With this demo code, you get to test the board the moment you receive it! While connected to your computer, a new CIRCUITPY drive appears. Explore and edit the demo code (code.py & lib folder) with any code editor you like, save any changes to the drive and you shall see it in action in no time. That's why we embrace CircuitPython – it's very easy to get started. Wish to use other programming lauguages? Sure, you are free to use MicroPython and C/C++ for Pico/RP2040.

The Arduino Giga R1 WiFi brings the power of the STM32H7 to the same form factor as the popular Mega and Due, being the first Mega board to include onboard Wi-Fi and Bluetooth connectivity. The board provides 76 digital inputs/outputs (12 with PWM capability), 14 analog inputs and 2 analog outputs (DAC) all easily accessible via pin headers. The STM32 microprocessor with dual-core Cortex-M7 and Cortex-M4, together with onboard memory and audio jack enables you to perform machine learning and signal processing on the edge. Microcontroller (STM32H747XI) This dual core 32-bits microcontroller allows you have two brain talking to each other (a Cortex-M7 at 480 MHz and a Cortex-M4 at 240 MHz) you can even run micropython in one and Arduino in the other. Wireless communication (Murata 1DX) Whether you prefer Wi-Fi or Bluetooth, the Giga R1 WiFi got you covered. You can even quickly connect to the Arduino IoT Cloud and keep track of your project remotely. And if you are concerned about the security of the communication, the ATECC608A keeps everything under control. Hardware ports and communication Following the legacy of the Arduino Mega and the Arduino Due, the Giga R1 WiFi has 4x UARTs (hardware serial ports), 3x I²C ports (1 more than its predecessors), 2x SPI ports (1 more than its predecessors), 1x FDCAN. GPIOs and extra pins By keeping the same form factor of the Mega and the Due, you can easily adapt your custom made shields to the Giga R1 WiFi (remember this board works at 3.3 V though!). Also, additional headers have been added so that the total number of GPIO pins is now 76, and two new pins have been added: a VRTC so you can connect a battery to keep the RTC running while the board is off and an OFF pin so you can shut down the board. Connectors The Giga R1 WiFi has extra connectors on board which will facilitate the creation of your project without any extra hardware. This board has: USB-A connector suitable for hosting USB sticks, other mass storage devices and HID devices such as keyboard or mouse. 3.5 mm input-output jack connected to DAC0, DAC1 and A7. USB-C to power and program the board, as well as simulate an HID device such as mouse or keyboard. Jtag connector, 2x5 1.27 mm. 20-pin Arducam camera connector. Higher voltage support: In comparison with its predecessors that support up to 12 V, the Giga R1 WiFi can handle a range of 6 to 24 V.
