The following is the original (-01) schematic, which was never publically released. The following changes were made in -02:
* MOSI/MISO was switched on Atmel device (requires PCB fixon -01, or PCB will not work)* TST connected to ground (requires PCB fixon -01, or PCB will not work)
* CLKI pull down
* GPIO3 is now optionally in control of 4066 instead of being hardwired
