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 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

Associate
LED pin (pin 15) and the commissioning button pin (pin 20). The Associate LED will flash differently
depending on the state of the module, and a pushbutton attached to pin 20 can enable
various deployment and troubleshooting functions without having to send UART commands.
If analog sampling is desired, VRef (pin 14) should be attached to a voltage reference.
