Motor Driver TReX Jr Dual DMC02

Pololu TReX Jr dual motor controller (MC33887), lower-power version of the TReX. Controls two bidirectional motors and one unidirectional auxiliary output via RC, analog or serial (RS-232 / TTL). Supply up to 24 V.

• Supply voltage: 5–24 V
• Primary outputs: 2 bidirectional, 5 A peak, up to 2.5 A continuous per channel (parallelable to ~5 A continuous)
• Auxiliary output: 1 unidirectional, 10 A continuous
• Speed control: 128 steps each direction
• Input channels: 5 (RC or analog)
• Serial: RS-232 and TTL, baud 1200–115200
• Logic voltage: 2.7–5.5 V
• Current sense: 0.5 V/A (digitized 0–255)
• Max PWM frequency: 10 kHz
• Reverse-voltage protection: yes
• Dimensions: 1.75" × 1.75" × 0.5" (0.3" without connectors)

Same control model as TReX (BEC, mix-mode, calibration, serial options, safe-start).

Note: Works as an ESC without serial; full features require the serial interface.
