BlueRobotics New Product: the Thruster Commander! Get up and running quickly with this multipurpose thruster controller.
Most ESCs do not accept simple knob- or button-inputs, instead communicating via pulse-width modulation (PWM) signals.
The Thruster Commander converts up to two potentiometer (knob) inputs to two separate PWM output signals that can be used to control ESCs.
This allows you to run BLDC motors without the need for a complex onboard computer system.
