## What it is
VESC is the open-source firmware for the VESC DC/BLDC/FOC motor controllers, written in C for STM32-based boards. It supports many hardware board targets and is configured and flashed via the companion VESC Tool application.

## Use cases
- control brushless motors with field-oriented control
- build firmware for an electric skateboard or e-bike ESC
- customize motor controller behavior for robotics projects
- flash and tune a VESC hardware controller
- implement FOC motor control on STM32

## When to choose
- you own or build VESC-compatible motor controller hardware
- you need open-source, customizable BLDC/FOC motor control firmware
- you want to tweak or extend motor controller behavior at the firmware level

## When to avoid
- you need a plug-and-play ESC without building firmware
- your motor controller hardware is not VESC-compatible
- you only want a GUI tuning tool without touching firmware (use VESC Tool instead)
