Pin Definitions and Ratings
Transmitter (#27980)
Transmitter Supply Current:
Receiver (#27981)
Receiver Supply Current:
PDN
Pulling the power down (PDN) line low will place the transmitter/receiver into a low-current state. The
module will not be able to transmit/receive a signal in this state.
RSSI (receiver only)
Received Signal Strength Indicator. This line will supply an analog voltage that is proportional to the
strength of the received signal.
