STMicro STSPIN220 Low-Voltage Stepper Motor Driver Carrier
Ensure precision with 1/256 microstepping
Operate efficiently from 1.8V to 10V
Handle up to 1A per phase without heat sink
Integrate easily with A4988 pinout compatibility
Protect with thermal, current, and circuit safeguards
The STMicro STSPIN220 Low-Voltage Stepper Motor Driver Carrier is an advanced breakout board designed for precision control of bipolar stepper motors. Featuring microstepping capabilities down to 1/256-step, this module operates efficiently within a voltage range of 1.8 V to 10 V, making it suitable for applications where conventional drivers fall short. It delivers up to 1 A per phase continuously without the need for a heat sink or forced air flow, with a peak capacity of up to 1.3 A. The module is engineered with a pinout and interface closely resembling that of the A4988 carriers, enabling seamless integration as a drop-in replacement in various systems. Key features include over-temperature thermal shutdown, over-current shutdown, and short circuit protection, ensuring robust performance. Constructed on a 4-layer, 2 oz copper PCB, it offers enhanced heat dissipation, complemented by an exposed solderable ground pad beneath the driver IC. The module measures 3x3 mm and includes one 1×16-pin breakaway 0.1″ male header for connectivity.
