This repository contains the hardware designs (KiCad) and embedded software (ESP-IDF) for a 3-phase brushless DC (BLDC) motor controller.
The project was developed as part of modernizing the educational equipment in the embedded systems laboratory at SeAMK. The old 8-bit ATmega architecture was upgraded to a modern 32-bit ESP32-C6 platform. The new motherboard was designed to directly support the laboratory's legacy analog and digital input/output expansion boards, preserving compatibility with the existing educational environment.
