Juicebox: Hardware
Overview
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?

Full Protel project (inclues past revs), as well as other project files can be downloaded at:

http://sourceforge.net/projects/juicebox/

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.
