For next version, a list of improvements;

  • Powerled, atm its nearly impossible to see if its on (unless the screen turned on, quite late in boot)
  • Powerswitch , atm i just remove battery
  • External access to uart0 , for debugging
  • Internal powerbus , need less powerwires going all over the place , this might save ~10 wires internally.
  • More internal space in case , i didnt really account for wires taking this much space.
  • Access to SD card
  • Camera!
  • Sound!
