Controllers
Motor controller modules are small, fully integrated stepper motor controllers designed to drive bipolar stepper motors used in compact motion systems such as motorized lenses, robotics, precision stages and automation projects. Each module combines the microcontroller and motor drivers on a tiny board, making them easy to embed directly into space constrained designs without external driver electronics. Using these controllers simplifies development, reduces wiring and PCB size, and provides reliable, precise multi-axis motion control out of the box. While USB is commonly used for power and communication, the controllers also support alternative control interfaces such as UART, I²C, GPIO and other serial buses, allowing seamless integration with embedded hosts and custom systems.
