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.

This version of our MP6602 Stepper Motor Driver Carrier ships with male header pins installed, so no soldering is required to use it with an appropriate 16-pin socket or solderless breadboard. Please see the MP6602 Stepper Motor Driver Carrier product page for more information about the driver.
