2.1.1.4 TXD Input (J3 or TP5)

The TXD (pin 1) of the transceiver, transmit data, is routed to J3 and TP5. The signal path to the J3 header is pre-installed with a 0Ω series resistor, R16. An optional pullup resistor to VIO can be installed on R15, an optional pulldown resistor to GND can be installed on R18, and an optional filtering capacitor can be installed on C5.
