This is a level converter to change TTL serial (TX only) output to pseudo-RS232 levels as required by FrSky telemetry receivers.
To use, solder male servo headers on both sides, plug "out" side to FrSky receiver (for example, D8R) telemetry port, remove 1st (TxD) pin from the "in" side and plug the servo header into any socket which provides ground and +5V, then connect the removed TxD pin into "tx" connector on Naze32. See image for details.
NOTE: This adapter is BUILT IN on current (rev5) version of Naze32. It's only required for older (rev4 or below) hardware.
