Repeat Robotics AM32 ESC


“Gosh! Software is eating the world today. And open source is everywhere. I wonder why no one has created an open-source firmware load for combat robotics ESCs?”

Wonder no longer! Brought to us by our friends at Repeat Robotics, this ESC uses the open source AM32 ESC firmware to drive your bot. This particular setup of AM32 is especially designed for combat robotics brushless drivetrains. The 35A Repeat drive AM32 ESC sports custom AM32 firmware that’s pre-programmed for smooth bi-directional movement. We take all the guessing out of brushless drive, and because it’s open source, we get the best software that the world’s minds can come up with! You can read about the AM32 phenomenon on Oscar Liang’s blog.

Several of you have asked when we would start offering AM32. We heard you! And here you are.

This firmware and ESC combination was specifically designed for use with Repeat Robotics’ brushless drive motors like the Repeat Drive Mk3 and the Repeat Drive Max, but it can generally be used with any antweight or beetleweight motors with minimal tweaking.

These ESCs have the power to handle up to 6S!

NOTE: This speed controller is is for brushless motors only, and can be used to control brushless drive motors but NOT brushed drive motors.

Input Voltage 3S-6S Lipo. Comes with 470uF capacitor to add to the ESC power leads for 6S operation.
Weight 5g
Weight 0.18oz

AM32 standard features, straight from its official description:

  • KISS standard ESC telemetry
  • Variable PWM frequency
  • Sinusoidal startup mode, which is designed to get larger motors up to speed
  • Stuck motor protection
  • Programmable through the AM32 esc config tool available HERE

A great wiring diagram, thanks to Georgia Tech’s RoboJackets Wiki can be found here: DiagramWiring diagram for ESCs driving wheel and weapons motors

Note that the Repeat Drive AM32 ESC would be used in this instance as the controllers for the drive motors in the wiring diagram.  All controllers are driven from the same battery, as you can see from the diagram.

NOTE: This speed controller is forward and reverse, and is recommended to control brushless drive but NOT brushed drive motors.
