More info


Jrk G2 21v3 USB Motor Controller is a single-channel DC motor driver. The voltage supplying the motors ranges from 4.5 to 28 V. The controller has one channel with a capacity of 2.6 A at constant power consumption. The control can be carried out via the USB port, TTL serial interface, I2C, RC receiver signal or via analog input. The controller enables easy implementation of a closed loop of engine speed control by connecting an analog or frequency input. It also allows configuration of engine operation parameters via a USB interface and a free application.
