Pololu TReX Jr Dual Motor Controller DMC02
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
1.75" x 1.75" x 0.5" (0.3" height without connectors)
1 unidirectional, 10 A continuous
RC servo pulses, analog voltages, or serial commands; master interface set by mode-select jumper
5 (RC servo pulses or analog voltages)
12-bit resolution, 1 us accuracy
supports 11 common baud rates ranging from 1200 to 115,200 bps
Allows multiple Pololu servo and motor controllers on one serial line
Allows both motors 1 and 2 to be simultaneously set with just three bytes
* Battery Elimination Circuit (BEC) jumper lets the TReX Jr optionally power your RC receiver or analog controller
* mix-mode jumper allows for single-stick motor control of differential-drive robots
* automatic calibration for your particular RC or analog controller (the TReX Jr can learn the channel ranges)
Options accessable through the serial interface
* all five high-resolution channel input values are available
* remapped channel input values show what the TReX Jr would do if it were in control
* optional 7-bit cyclic redundancy checking to ensure command/data validity
* calibration values can be explicitly read and set
* each channel can be reversed and parabolically scaled
* current limit, acceleration, and maximum motor speed settings
* safe-start requirements prevent accidental motor activation at power-up
* optional automatic motor shutdown on serial error, timeout, or input channel noise
