Low-voltage stepper motor controller TME offer includes a stepper motor controller by POLOLU, based on the STSPIN220 chip. This product is available in two versions – with and without soldered connectors. The module can cooperate with bipolar stepper motors at 1.8V to 10V operating voltage and maximum current of 1.1A per phase (without using a heatsink). The controller offers step resolution from full steps to 1/256. Selection is made by appropriate configuration of signals on M0-M4 inputs.
In terms of size and layout, the module is compatible with popular A4988 driver boards. It can work directly with systems operating at 3.3V and 5V, e.g. Arduino or ESP32. As is usually the case with POLOLU products, the STSPIN220 is easy to use and has a number of protections: against overheating, short circuit and over current. Apart from a 100μF expansion capacitor (between VMOT and GND pins), the module requires practically no external components.

POLOLU-2876 and POLOLU-2877 controllers have another advantage – they enable active limitation of control current. Thanks to this functionality, it is possible to exceed the maximum allowable voltage supplied to the motor coils, which allows to increase its stroke speed. In order to avoid damaging the components, the maximum current value must be calculated and the limiter properly adjusted. Here, a detailed video instruction prepared by POLOLU may come in handy.
