Design Notes:
•All I/O is 3.3V TTL.
•All inputs are weakly pulled High (20k) and may be left floating during normal operation. When implemented, RTS will be weakly pulled Low.
•Minimum Connections: VCC, VPA, GND, TXD, & RXD.
•Signal direction is with respect to the transceiver.
•Unused pins should be left disconnected.
