PCB design for SPI adapters (HATs)
In this repository we will keep PCB designs done in KiCAD for SPI adapters we use. This PCB hardware work uses the CERN Open Hardware Licence Version 2 in the weakly reciprocal version. Be aware that this is experimental work mostly done for research and mass-producing this PCB's is not permitted without our written consent. Fabricating and selling hardware also implies that you need to provide support / fixes and maintain your code examples up to date.
