This lower-power, smaller, and lower-cost version of the TReX is the ultimate general-purpose motor controller for small motors: it has a wide operating range (5 to 24 V), delivers 2.5 A continuously per motor, provides current sensing on the two main channels, and it features the TReX triple interface that allows you to control motors from a serial line (RS-232 or TTL), radio control (RC) receiver, or analog voltage source such as a potentiometer.
