A remix of Rommana that supports a Nice Nano v2 / Supermini NRF 52840 and Single Switch PCBs.

This remix introduces the following changes, on top of the original Rommana:

  • Make the switch holders thicker (5mm), so that the PCBs can sit flush.
  • Add switch lockers to the switch holders.
  • Increase the height of the base of the body in 5mm, to accommodate a 500mAh battery.
  • Adjust screw holes.
  • Add a detachable components socket that holds:
    • MCU: nice-nano v2 or Supermini NRF52840.
    • On/off switch or an USB-C breakout board.
    • Reset button.

These changes were made preserving as much as possible the original design.
