This repository provides a low-cost, open-source design for a 12S Electronic Speed Controller (ESC) geared towards heavy-lift multirotor applications. It is designed to work with ESCape32, an open-source 32-bit ESC firmware.
The goal of this ESC design is to maximize the performance-to-cost ratio by utilizing readily available components and open-source firmware while maintaining electrical and thermal characteristics that meet or exceed those of commercial ESCs in the same class.
This project aims to offer a competitive alternative to proprietary ESCs used in drones, robotics, and other high-power applications.
- STM32G431 processor
- 24MHz HSE crystal resonator
- 12S input (up to 50.4V)
- Full support for ESCape32
Note
Although these are designed for 12S, the actual hardware is rated for 100V which is nearly double.
