This is a breakout board for the MPS MP6602 microstepping bipolar/unipolar stepper motor driver, which features a serial interface and stall detection. It operates from 4.5 V to 35 V with a maximum current limit of 4 A, which it can run at continuously on our carrier board without a heat sink or forced air flow. The SPI interface allows configuration of the current limit, step mode (6 step modes from full-step through 1/32-step), decay mode off time, and stall detection, and it can also be used for stepper motor control. The driver also features built-in protection against under-voltage, over-current, and over-temperature conditions. This version does not include header pins.
