DRV8434S SPI Stepper Motor Driver Carrier, Potentiometer for Max. Current Limit
This breakout board for TI’s DRV8434S microstepping bipolar stepper motor driver operates from 4.5 V to 48 V and can deliver up to approximately 1.2 A continuous per phase without a heat sink or forced air flow (2 A peak). The SPI interface allows configuration of the current limit, step mode (11 step modes from full-step through 1/256-step), decay mode, and stall detection. The driver also features built-in protection against under-voltage, over-current, and over-temperature conditions. This version of the board uses an on-board potentiometer for setting the maximum current limit, and SPI can be used to set the actual current limit to intermediate values in increments of the set maximum/16.
