Interfaces

This chapter documents the interfaces between Telega and the power stage, motor, and external systems (such as the flight controller or any other entity responsible for issuing commands to the motor controller).

Warning

Not more than one interface should be used at any given time for issuing commands. Sending conflicting commands over different interfaces may lead to unpredictable behavior.

Important

Telega does not support USB because this interface is ill-suited for power electronics. Certain models of some motor controllers are equipped with a built-in USB port intended for diagnostics only; it should not be used in production.
