Pinebook Pro 'xtreme'

[tllim]

I do repeat *my* request : not more power or memory, but a "geek port" that allows to plug "hats" and do experimentation or command/control directly from the PBP. Maybe a USB-C extension would fit the job but it would be great to control electronic stuff. So I²C, SPI, UART, CAN, Modbus, ...

I second that motion!  

One of the ideas I raised with the original Pinebook was that since the USB, headphones socket and microSD socket were on a daughterboard on the left side of the Pinebook, that it could be swapped out for another module, which would expose a 5x2 female header (why? Because that conveniently perfectly fits in the hole in the side for the USB socket!) which would then allow access to a bunch of GPIOs...

But having said that, it's probably better (better in this case meaning easier, more flexible, safer) to have an Arduino Nano plugged into the USB... allowing reliable I²C, SPI, etc with a dedicated processor.

Actually someone can just expend the side daughter board to implement that GPIO expansion function. The side board schematic has been released, Pinebook and Pinebook Pro have same daughter board :-) If this interest is high, I can released the side daughter DSN and Gerber file.
