4 Flexible Input Control Modes

Standard potentiometer or hall throttle (0.8–4.2V), joystick mode, direct PWM input (0–95%), or RC PWM receiver input 1.5ms ±1ms. Fits any installation out of the box.

Regenerative Braking

Captures kinetic energy back into the battery during braking. Essential for EV conversions and forklifts where efficiency matters. 2-quadrant operation in one direction.

High-Speed 32-bit Cortex Processor

18 kHz switching frequency for whisper-quiet operation. Precise 0–98% duty cycle control with adjustable acceleration ramp from 0 to 40 seconds.

Smart Current Limiting

Adjustable normal current limit from 0–50A, with 70A peak capacity. Protects both motor and controller from overload, extending system lifespan significantly.

Full Serial Communication Control

Completely controllable via TX/RX serial connector with extended parameter access. Integrate directly with PLCs, microcontrollers, Raspberry Pi, Arduino, and more.

Compact & Lightweight

Just 65 × 76 × 28 mm and 100 g without heatsink. M6 high-current connections on all power terminals. Designed for tight installations in EVs, boats, and industrial machinery.

Used this in an electric cargo bike conversion. The regenerative braking is noticeable and really extends range on long descents. Serial control worked perfectly with my Arduino.
