Maker Pi RP2040

Image of Board

Cytron Maker Pi RP2040 features the RP2040 chip, embedded on a robot controller board. The board also comes with 2-channel DC motor driver, 4 servo motor ports and 7 Grove I/O connectors, ready for your next DIY robot/motion control projects.

The DC motor driver onboard is able to control two brushed DC motors or single bipolar/unipolar stepper motor 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 test code. Vmotor for both DC and servo motors depends on the input voltage supplied to the board.

Maker Pi RP2040 has lots of LEDs for troubleshooting and 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.

CircuitPython is preloaded on the Maker Pi RP2040 and it runs a simple demo program right out-of-the-box. It can also be programmed with C/C++ (natively or with Arduino IDE support) or MicroPython.

Absolute Newest

Every time we commit new code to CircuitPython we automatically build binaries for each board and language. The binaries are stored on Amazon S3, organized by board, and then by language. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.

Past Releases

All previous releases are listed on GitHub, with release notes, and are available for download from Amazon S3. They are handy for testing, but otherwise we recommend using the latest stable release. Some older GitHub release pages include the same binaries for downloading. But we have discontinued including binaries as assets on newer release pages because of the large number of files for each release.
