DynOSSAT-EDU OBC
by BH Dynamics
DynOSSAT-EDU is the first open source PocketQube educational kit compatible with CircuitPython and Arduino.
This plaform is equipped with all the necessary modules for the operation of a nanosatellite (PocketQube) in Low Earth Orbit (LEO) that would serve as a device for teaching, training, and driving curiosity about the philosophy and technology related to NewSpace.
This is the On-Board Computer (OBC), the module responsible for managing the satellite and process sensor data. It integrates a 9-axis IMU, a gas sensor, a temperature sensor and carries a powerful ATSAMD51.
Hardware is licensed under CERN OHL v1.2.

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.
