## What it is
XDrive is open-source firmware (with hardware schematics and enclosure designs) for a stepper motor driver featuring a multi-function interface and closed-loop encoder-based control. It includes a main control application, a bootloader for USB firmware updates, circuit diagrams, and documentation.

## Use cases
- build a closed-loop stepper motor driver
- flash stepper motor firmware over USB
- control stepper motors with encoder feedback
- customize motor controller firmware for CNC or 3D printers
- learn embedded motor control in C

## When to choose
- you want an open-source closed-loop stepper driver you can build and modify
- you need hardware schematics and firmware together for a motor controller project

## When to avoid
- you need a plug-and-play commercial driver without soldering or flashing
- your project uses servo or DC brushless motors instead of steppers

## Facets
- artifact type: application
- maturity: active
- function: embedded, cryptography
- domain: embedded-systems, hardware, robotics
- platform: embedded, c
- tags: stepper-motor, closed-loop-control, motor-driver, encoder, stm32, bootloader, usb-update
