Documentation inspired by 12S ESC.

This board design is part of Kenny’s WARG EE Fall 2024 co-op.

Requirements

• Should be powered by a 3S (12V) battery input.

  • In the context of integrating with the ELRS board, an XT60 connector should be provided, and additional 5V, GND, and PWM headers should be placed. The ESC’s “BEC” is already integrated into the ELRS boardPWM input from a header pin should placed.

• Must use the AM32 open-source firmware for motor control. (https://am32.ca)

  • This uses a sinusoidal algorithm to control the BLDC. (no FOC)

  • Has a strict MCU compatibility list (we would preferably use a smaller ST chip)

Microcontroller Selection

AM32 provides a list of supported microcontrollers in their GitHub repository’s README file. Additionally, there is an MCU “target compatibility list” that can be found inside of the code.
