STBY   Input for transmitter stand-by control pin is
pulled to VCC for transmit operation and GND
for stand-by mode. Internally pulled-up to VCC.

REG-EN In a regulated module, this pin powers on the
module with a 2-16V supply input. Pulling this
pin low disables module. In a non-regulated
module, this is a no connect.
11
17
+5V    In a regulated module, this is a 5V output from
the onboard regulator when REG-EN is high (2-
16V). In a non-regulated module, this is the
4.75V to 5.5V power supply input.

18
+VIN   In a regulated module, this is the power supply
pin of the module. Input 5-16V to power a
regulated module. In a non-regulated module,
this is a no connect.
