Does anyone know of anything supporting the gpio flatflex connector on the uconsole? even if it’s just a breakout board/connector? I’m wanting to look at what’s available on it to potentially add an NFC reader to my uconsole (half-baked/prototyping at first). If it’s got SPI or I2C then it’d let us make a board that could go on the outside of the case (or just the coil). That way I could use my hardware 2fa key over NFC instead of replacing the lte expansion board (also an option but i’d rather do it via the gpio header to avoid that.
From what folx have discovered looking at the various schematics (now all on the github), there is I2C from the ID bus available on the GPIO FFC, but pretty much nothing else that is either unallocated or shareable.
