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
