An open source “swiss army knife” for hardware and IoT applications. This board is designed for quickly prototyping a wide range of makerspace, university, and science-related projects.

The SAM32 features a 120 MHz SAMD51 main processer, an ESP32 WROOM co-processor, native USB handling via CircuitPython, micro SD card socket, LiPo battery charging, 42 available I/O pins, a NeoPixel, and pin compatibility with Adafruit Feather Wings.

Release Notes for 5.1.0

CircuitPython 5.1.0-rc.0

This is the latest unstable release of CircuitPython that will work with the SAM32.

Unstable builds have the latest features but are more likely to have critical bugs.

Release Notes for 5.1.0-rc.0

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.
