IR LED
IR + (Pin 2, ROUND) is used to connect an IR LED - either direct-solder the LED or attach the LED via a cable.
The LONG leg of the LED goes in the ROUND hole. The SHORT leg of the LED goes in the SQUARE hole.

UART2/PPM - Serial RX or PPM RX + Telememetry
Use a standard 3 pin cable on pins 1-3 to attach to either a Serial RX receiver or a PPM receiver. Use pin 4
as telemetry output when using PPM.
5v
is also supplied when connecting via USB.
Note: When using a Serial RX receiver the TXD (T2) pin cannot be used for telemetry. Use UART5 TXD
instead.
NOTE: There is a recevier connector on the bottom of the board which you may find easier to use.
