A modchip-style SOIC8 EEPROM to Stemma QT adapter #STEMMAQT

Francois Gervais had designed a very clever way to get a STEMMA QT / Qwiic connection on a circuit board, if there is a SOIC8 footprint EEPROM onboard. Using an OSH Park flex PCB to overlay the EEPROM, like a game console modchip, is the key. The PCB’s other end has a standard connector.

See the design on OSH Park and on GitHub.
