Introducing the Cytron Maker RP2040<\/a><\/h2>\n\n\n\n

Cytron Maker Pi RP2040 features the first microcontroller designed by Raspberry Pi – RP2040, embedded on\u00a0a robot controller board. This board\u00a0comes with a dual-channel\u00a0DC motor driver, 4 servo motor ports and 7 Grove I\/O connectors, ready for your next DIY robot\/motion control\u00a0project. Now you can build\u00a0a robot while trying out the new RP2040 chip.<\/p>\n\n\n\n

The DC motor driver on board is able to control 2x brushed DC motors or 1x\u00a0bipolar\/unipolar stepper motor rated from 3.6V to 6V, providing up to 1A current per channel continuously. The built-in Quick Test buttons and motor output LEDs allow a 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.<\/p>\n\n\n\n

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.<\/p>\n\n\n\n

There are three ways to supply power to the Maker Pi RP2040 –\u00a0via USB (5V) socket, with a single cell LiPo\/Li-Ion battery or through the VIN (3.6-6V) terminals. However, only one power source is needed to power up both controller board and motors at a time.\u00a0Power supply from all these power sources can all be controlled with the power on\/off switch onboard.<\/p>\n\n\n\n

Cytron Maker Pi RP2040 is basically the Raspberry Pi Pico<\/a> + 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.<\/p>\n\n\n\n

CircuitPython is preloaded on the Maker Pi RP2040 and it runs a simple demo program right out of the box. Connect\u00a0it to your computer via USB micro cable and turn it on, you will be greeted by a melody tune and LEDs running light. Press\u00a0GP20 and GP21 push buttons to toggle\u00a0the LEDs on\/off while controlling any DC and servo motors connected to it to move and stop.\u00a0With this demo code, you get to test the board the moment you receive it!<\/p>\n\n\n\n

While connected to your computer,\u00a0a 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\u00a0and you shall see it in action in no time. That’s why we embrace\u00a0CircuitPython<\/a>\u00a0–\u00a0it’s very easy to get started. Wish to use other programming languages?\u00a0Sure, you are free to use\u00a0MicroPython\u00a0and\u00a0C\/C++\u00a0for Pico\/RP2040. For those of you who love the Arduino ecosystem, please take a look at this\u00a0official news<\/a>\u00a0by Arduino and also the\u00a0unofficial Pico Arduino Core<\/a>\u00a0by Earle F. Philhower.<\/p>\n\n\n\n
