UART Telemetry Output
The UART output is not isolated from the signal input connections. The output must be connected to a different device to the signal generator. Failure to do so will result in permanent damage to the unit.
HV Pro units produced after Feb 2020 will contain a separate header for the UART output stream. If your unit does not contain this header, please contact APD on how to proceed.
The UART output of the ESC matches the logged data contents. The data stream will begin when the ESC receives a valid throttle signal (arming is not necessary). Datarate is 115200 Baud.
