Adafruit is an Open Source Hardware and Software company. To that end, Adafruit is working to submit many of their boards for certification by the Open Source Hardware Association. According to OSHWA:
The certification program exists to make it easy for creators and users to identify hardware that follows the community definition of open source hardware maintained by OSHWA. Hardware projects that display the certification logo are licensed and documented in a way that makes it easy for users to use and build upon them.
By registering their boards with OSHWA, Adafruit aims to ensure users that the products they sell are open-source, and easy to learn about.
Here are the boards that have been submitted in the last week:
