Simmel Board
by Simmel Project
Simmel is a platform that enables COVID-19 contact tracing while preserving user privacy. It is a wearable hardware beacon and scanner which can broadcast and record randomized user IDs. Contacts are stored within the wearable device, so you retain full control of your trace history until you choose to share it.

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.
