KiCad versions of my circuits
Many of my boards have the Open Source Hardware logo on them. Using this logo requires having an open source license and publishing the source. In order to support this, I have the URL of this repository engraved onto the boards themselves.
I have made a release for the Wearable Pocketometer boards, and intend to make a release each time I have a board made.
All boards which have been released since September 2020 have enough information to construct a bill of materials. This is in the form of Digikey part numbers attached to each part in the KiCad .sch files.
