The A100S was designed specifically for use in Beatleweight and Featherweight combat robots. It runs the extremely popular VESC®*-Project firmware. 

Featherweight Weapon - Slice of LiFe (Blue)
12S A100S with XAG A16 motor


Heavyweight Drive - Triforce (Circle)
12S A100S with XAG A16 motor


Included in the package

  • A100S V4
  • LCC40 motor connector with crimp pins for 10AWG
  • LCB40 battery connector with crimp pins for 10AWG
  • Pico-clasp 20pin connector shell + 10 double ended precrimped wires  (enough to populate the connector)

Quick tips on setup

  • We recommend detecting motors using the FOC motor setup wizard. This will automatically find the correct settings for your motor.

UPDATE needed:

Motor Commutation Modes

  • FOC - Sensorless, Hall Sensors, HFI
  • BLDC - Sensorless, Hall Sensors
  • DC - For driving brushed DC motors on outputs A and C.

Motor Control Modes

  • Current - Controls current (torque) to motor irrespective of duty cycle
  • Duty Cycle - Controls duty cycle sent to motor irrespective of current
  • PID RPM control - Controls motor RPM using a PID loop

Control Interfaces

  • PPM
  • UART
  • CANBus (supports UAVCANv0)
  • ADC

Voltage Rating

  • 8-80v, 18 cell LiPo maximum.

Safety Features

  • Active current limiting - actively limits motor current to stay below programmed limit
  • Software over current protection - stops motor running if the current exceeds programmed limit
  • Slow temperature cutoff - ramps down motor current when approaching programmed max temperature
  • Battery voltage cutoff - ramps down motor current when approaching programmed voltage cutoff
  • Under / Over Voltage cutoff - stops motor running if the voltage goes outside the programmed range


Programming features - using VESC®* Tool
