FOC Integrated Driver Board
This is a sensored FOC driver board with onboard driver and MCU; the BLDC motor can be controlled externally via serial port.
Integrated Sensored FOC Driver
The original intention of this project was to build a force-feedback CW key and learn the principles of sensored FOC (the FOC algorithm is indeed difficult, hence the project name difficultyFoc ).
The driver board features an integrated design, including motor driver (MP6536) / magnetic encoder / MCU (STM32G031) / low-side bus current sampling, with external interfaces for serial port and debugging.
When paired with a low KV gimbal motor, it looks quite the part. When working against resistance, the MP6536 motor driver generates heat, so a small copper heatsink was added on top of the chip.
