The Pololu DRV8434S SPI Stepper Motor Driver Carrier, 2A Max. Current Limit 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 has the maximum current limit set to a fixed 2A, and SPI can be used to set the actual current limit to any of 16 evenly spaced values from 125 mA up to 2 A (i.e. in increments of 125 mA).
