PinePhone to RCA 7" tablet keyboard adapter plate
thingiverse
This is a frame to hold a pinephone in an RCA RKT773P tablet case with usb keyboard, which is the smallest keyboard I could find with scissor action switches at about 200mm wide. To use this, solder a usb cable to the pogo pins on the keyboard (red on left, then white, green, and black on right), and plug into a usbc host adapter on the pinephone. All the cables should tuck neatly into this adapter, and the usbc end can be carefully glued in place so the pinephone can slide in and out easily.
