Hardware is designed in Protel 99SE. Current rev is
x02. Change list for x03:
- Something is wrong with battery charger; use a different chip?
- Add pads for switches at edge of board in addition to membrane patterns
- Add pads for additional audio jack at opposite side of board
- Add low voltage cutoff for battery
- Add battery disconnect when externally powered
- Maybe use SD slot in place of MMC slot?

project files can be downloaded at:
Programming is via the 10 pin flat cable. I have a custom
adapter which works with PonyProg and uisp, and also has an
RS232 level shifter for the tty interface. I will get the
files up for that board RSN.
