## Description

This version of Pololu's DRV8434S SPI Stepper Motor Driver Carrier, 2A Max. Current Limit ships with male header pins installed as shown in the main product picture, so no soldering is required to use it with an appropriate 16-pin socket or solderless breadboard. Please see the [DRV8434S SPI Stepper Motor Driver Carrier, 2A Max. Current Limit product page](https://core-electronics.com.au/drv8434s-spi-stepper-motor-driver-carrier-2a-max-current-limit.html) for more information about the driver.

**Notes:**

1Inputs below 6 V reduce the maximum settable current limit. With 4.5 V in the maximum settable limit is 1.75 A.2Not intended for use with 48V batteries, which can be well above nominal when fully charged.3Without a heat sink or forced air flow.4With sufficient additional cooling.5Logic high threshold varies for two-state, tri-state, and quad-state pins. See datasheet for details.6Absolute maximum voltage on any input is 5.75 V. **File downloads**

    This is a library for [Arduino](https://core-electronics.com.au/hardware.html) that helps interface with a [DRV8434S](https://core-electronics.com.au/drv8434s-spi-stepper-motor-driver-carrier-potentiometer-for-max-current-limit.html) stepper motor driver. It uses the Arduino SPI library to communicate with the SPI interface (nSCS, SCLK, SDI, and SDO) of the DRV8434S.
