Motor DriverTReX Dual DMC01

Pololu TReX dual motor controller (VNH2SP30). Controls two bidirectional motors and one unidirectional auxiliary output via RC servo pulses, analog voltage, or serial (RS-232 / TTL).

• Supply voltage: 6–16 V
• Primary outputs: 2 bidirectional, 30 A peak, up to 13 A continuous per channel (parallelable to ~25 A continuous)
• Auxiliary output: 1 unidirectional, 15 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: 0.13 V/A (digitized 0–255)
• Max PWM frequency: 19.5 kHz
• Reverse-voltage protection: yes
• Dimensions: 1.9" × 1.9" × 0.8"

RC/analog features: BEC jumper, mix-mode for differential drive, automatic channel calibration. Serial options include CRC, channel remapping, current/acceleration limits, coast/brake in deadband, firmware upgrade.

Note: Works as an ESC without serial; full features require the serial interface. Safe-start and optional shutdown on serial error, timeout or input noise.
