## What it is
An open-source hardware project providing compact closed-loop stepper motor drivers for NEMA form factor motors, with schematics, PCB files, and firmware options like SimpleFOC. It offers precise 0.01° position control, silent operation, and interfaces such as USB, CAN-FD, UART, I2C, and SPI.

## Use cases
- drive a NEMA17 stepper motor with closed-loop position control
- build a CNC machine with precise motor positioning
- add silent smooth motion to a 3D printer
- control robot joints with encoder feedback
- build a camera or telescope stabilization mount
- learn FOC motor control on real hardware
- implement force feedback haptics with stepper motors

## When to choose
- you need precise closed-loop control of NEMA stepper motors
- you want open-source hardware you can modify or manufacture yourself
- you need compact drivers with CAN-FD, USB, or UART interfaces
- you want silent, energy-efficient stepper operation for robotics or CNC

## When to avoid
- you need a commercial license for products - the design is CC BY-NC-SA (non-commercial)
- you need a turnkey off-the-shelf driver rather than a board you assemble or source
- you need firmware support beyond SimpleFOC - the TunePulse firmware is still unreleased
- you need to drive motors other than NEMA form factor steppers or small BLDCs
