@maluka Starting with a bluetooth keyboard would be exactly the same. Strip everything, use the keys only, don't use BT and build from the ground up. The only difference is I don't have a BT keyboard case on hand.

@minimos The keyboard keys are only 19mm high, so it will be no problem to incorporate holes in the OH for the camera. However, solving hardware issues like this is not priority at the moment. Lets get a proof-of-concept first!

@DeeGee I had already found that chip. Problem is it runs on max 3.6 volt, where the jolla phone runs on 3.8 volts. And I don't have a special oven for cooking this kind of chip on the pcb

@youmeego Off-topic!

Anyone experience with NKRO, ghosting, pcb design?
