Design Notes:
• Minimum connections: VCC, GND, DOUT & DIN
• Minimum connections to support serial firmware upgrades: VCC, GND, DIN, DOUT, RTS & DTR
• Signal Direction is specified with respect to the module
• Module includes a 30k Ohm resistor attached to RESET
• Several of the input pull-ups can be configured using the PR command
• Unused pins should be left disconnected
