## What it is
miniFOC is an open-source Field Oriented Control (FOC) firmware and hardware scheme for brushless DC (BLDC) motors, designed to run on very cheap Chinese-made microcontrollers (GD32) for around $3 in parts. It provides a torque closed-loop controller controllable over a 3-wire UART port, with SVPWM modulation and support for torque, speed, and position control.

## Use cases
- control a brushless motor with FOC on a $3 budget
- replace noisy brushed motor drivers with quiet BLDC control
- drive a BLDC motor via UART commands
- implement torque closed-loop control for a gimbal or robot motor
- learn how field oriented control works on embedded hardware
- build low-cost motor controllers for robotics projects

## When to choose
- you need extremely low-cost FOC motor control hardware and firmware
- you want quiet, efficient BLDC control instead of brushed motors or ESCs
- you are working with GD32/STM32-class MCUs and UART-based motor control
- you want an open-source (AGPL-3.0) alternative to SimpleFOC or ODrive for simple torque control

## When to avoid
- you need sensorless FOC or current-loop control today (V2 is still in development)
- you need a mature, production-grade controller like ODrive with extensive community support
- your project requires position/speed closed-loop out of the box without additional tuning
- AGPL-3.0 licensing is incompatible with your product

## Facets
- artifact type: library
- maturity: active
