Picture of the X-Lite transmitter bay pinout . Couldn't find a picture of the module with pinout. The "first" five pins are the same pinout as the JR connector on the T8+. I like the picture because "first" could be either end.

Three connections are needed to the trainer port on the Devo10.
- trainer port tip to R9M PXX pin (PXX_OUT in picture)
- trainer port ring to R9M S.Port pin
- trainer port sleeve to R9M GND pin

The R9M Lite manual doesn't list max input voltage and don't know if the X-Lite pin labeled 6V is regulated or not. The power is up to you :)

Correct. In the devo10 the same uart is used for both serial output and voice. Voice is disabled when a serial protocol is in use.

Yes, zero to 63. There's more information in the user manual in the PXX protocol section.

i think there's a bug on the latest firmware for devo 10. i just upgraded tx firmware to the latest one. i've seen the new protocol but i haven't tried it yet cause suddenly my tx restart it self with this latest firmware.i have to figure it out first.
