DO Output data pin. CMOS level compatible.
SWEN Controls the operating mode of the receiver. When high, the
receiver is in sweep mode.When low, the module operates as a
conventional single-conversion superheterodyne receiver (fixed
mode) - this is the recommended mode of operation. This pin is
internally pulled-up to VCC.

SEL1 Reserved for future use. Must tie to ground.
SEL0 Programs desired Demodulator Filter Bandwidth. This pin is
internally pulled-up to VCC. See Table 1.
SHUT Shutdown mode logic-level input. Pull low to enable receiver. This
pin is 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.
+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.
+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.
