UART Telemetry Output

Details on the UART telemetry output on the UHV ESC

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.

Reading Datastream

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.
