 // But this does not work on FrSky radios since the telemetry lines of the internal and external modules are shared (hardware limitation).
 // On a STM32 module and with a simple hardware modification, you can go around this limitation using CPPM to send the trainer information to the radio.
 // Hardware modification: add a 1K resistor between the STM32 USART1 TX pin (Boot0 programming TX pin) and the radio bay pin 2.
