Image of Board

Introducing the Maker Uno RP2040, a revolutionary development board that combines the beloved Uno form factor with the powerful dual-core Arm Cortex-M0+ processor chip, the Raspberry Pi® RP2040. Packed with Maker Series goodness and enhanced features, this board is designed to elevate both your innovative projects and educational pursuits.

Comes with the handy Maker series goodness aimed to simplify digital making. Equipped with onboard LEDs for troubleshooting and visual effects, a ready-to-use programmable piezo buzzer, and push buttons, it’s perfect for kickstarting your project and learning process.

In addition to the ever-trusted female Uno Header, we provide the board Grove and Maker ports for quick sensors and modules connection and foolproof protection against misconnections.

Connect up to 4 servo motors simultaneously with our board’s dedicated servo port! Quickly integrate your servo motors without the hassle of using extra messy jumpers and worrying about insufficient current supply.

The board offers two power supply options - USB(5V) or with a single-cell LiPo/Li-Ion battery which also comes with automatic power selection, offering flexibility for various applications. Not only that, it comes with built-in charging circuit with overcharge and over-discharge protection circuit to charge the LiPo battery.

Last but absolutely not least, this board supports Arduino IDE, CircuitPython, and MicroPython programming. Whether you’re a seasoned developer or just starting, this versatile board invites you to explore, learn, and innovate with ease.

CircuitPython 9.1.0-beta.3

This is the latest development release of CircuitPython that will work with the Maker Uno RP2040.

Alpha development releases are early releases. They are unfinished, are likely to have bugs, and the features they provide may change. Beta releases may have some bugs and unfinished features, but should be suitable for many uses. A Release Candidate (rc) release is considered done and will become the next stable release, assuming no further issues are found.

Please try alpha, beta, and rc releases if you are able. Your testing is invaluable: it helps us uncover and find issues quickly.

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. These releases are even newer than the development release listed above. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.

Previous Versions of CircuitPython

All previous releases of CircuitPython are available for download from Amazon S3 through the button below. For very old releases, look in the OLD/ folder for each board. Release notes for each release are available at GitHub button below.

Older releases are useful for testing if you something appears to be broken in a newer release but used to work, or if you have older code that depends on features only available in an older release. Otherwise we recommend using the latest stable release.
