This project provides an AVR-based, USB accessible, single-axis motion controller that can fit into an USB-connector completely and therefore is probably the worlds smallest stepper motor controller. Here both, hardware schematics and all software components are provided.
Features
- USB connection
- 28,5 kHz maximum step clock, ≈5 Hz minimum step clock
- fine speed and acceleration steps
- support of one single stepper motor via step and direction signals
- motion acceleration (speed ramps)
- freely definable referencing modes
- one digital input expecting TTL logical level for usage with reference switch or as trigger input
- easy to use programming inteface (API) for integration in own applications
- open hardware
