Note: Our 350 series is one of the only controllers in market that can run motor with inductance as low as 3uh with low side shunts because of the super low noise and high performance components used.


  • Controller uses Open-Source motor control software VESC®-Project firmware by Benjamin Vedder. (VESC is a registered TM, owned by Benjamin Vedder)
  • Added 12v 1.2A (Not used for powering ESC) DC-DC Converter for powering accessories.
  • Added Bluetooth Onboard.
  • Field Weakening and MTPA (Maximum Torque Per Amp) are supported.
  • Plenty of CPU resources are left so you can make your apps for the controller.
  • Powered By STM32F4 microcontroller Running at 168MHZ.
  • Sensored and sensor-less FOC with auto-detection of all motor parameters
  • Current and voltage measurement on all phases.
  • Variable Regenerative braking.
  • Brushless, brushed DC motors, IPM motors are supported.
  • A GUI that is easy on the eyes.
  • Adaptive PWM frequency to get as good ADC measurements as possible.
  • Good start-up torque in the sensor-less mode (and obviously in the sensored mode as well).
  • The motor is used as a tachometer, which is good for odometry.
  • Duty-cycle Control, Speed Control, Current Control and Position Control.
  • Seamless 4-quadrant operation.
  • Interface to control the motor: PPM signal (RC servo), analog, UART, I2C, USB or CAN-bus.
  • Consumed and regenerated amp-hour and watt-hour counting.
  • Optional PPM signal output. Useful when e.g., controlling an RC car from a raspberry pi or an android device.
  • The USB port uses the modem profile, so an Android device can be connected to the motor controller without rooting.
  • Adjustable protection against
a) Low input voltage
b) High input voltage
c) High motor current
d) High input current
e) High regenerative braking current (separate limits for the motor and the input)
f) Rapid duty cycle changes (ramping)
g) High RPM (separate limits for each direction).
  • When the current limits are hit, a soft back-off strategy is used while the motor keeps running. If the current becomes way too high, the motor is switched off completely.
  • The RPM limit also has a soft back-off strategy.
  • Realtime Data logging and Monitoring.
