Project Status

Revision 1 boards and parts ordered 2011-03-13. Board built and working (but see revision 1 notes below) with HackTrack. The IOstrich Strich Labs product supersedes this board, dropping the LCD connection but keeping the GPIO expansion.

Revision 1 Notes

  • Shroud on LCD connector interferes with Backlight On jumper and Direct/I2C jumpers
  • Each female GPIO connector plugged into the male ones on the board interfere with each other
  • Almost every connector interferes with every other one
  • Pin 5 on the LCD needs to be tied low
