Design Notes:
• Minimum connections: VCC, GND, DOUT & DIN
• Minimum connections for updating firmware: VCC, GND, DIN, DOUT, RTS & DTR
• Signal Direction is specified with respect to the module
• Module includes a 50k Ω pull-up resistor attached to RESET
• Several of the input pull-ups can be configured using the PR command
• Unused pins should be left disconnected
