PyCubedv04 w/MRAM


Image of Board

⭐ Double-check the your PyCubed board version before updating firmware.

PyCubed is an open-source, radiation-tested small satellite framework programmable entirely in CircuitPython. Capable of all standard operating functions a small satellite might need, the PyCubed mainboard provides University and hobbyist teams an entirely open-source and sate-of-the-art hardware and software avionics solution for their satellite missions without having to spend tens of thousands of dollars for antiquated commercial products.

Yet PyCubed’s greatest value is its ease of programming & immense documentation. With nearly 100 detailed write-ups and tutorials, PyCubed’s online resources are available to everyone and even include a step-by-step guide that walks you from unboxing and LED blinking all the way through full-featured mission software examples.

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.
