Description
Reviews

This breakout board for TI’s DRV8434A microstepping bipolar stepper motor driver offers microstepping down to 1/256-step and operates from 4.5 V to 48 V. It can deliver up to approximately 1.2 A per phase continuously without a heat sink or forced air flow (up to 2 A peak). The driver has integrated stall detection and uses a ripple control algorithm that allows tight regulation of current level and increased motor efficiency. The module has a pinout and interface that are very similar to that of our popular A4988 carriers, so it can be used as a drop-in replacement for those boards in many applications. It features built-in protection against under-voltage, over-current, and over-temperature conditions.

This product is a carrier board or breakout board for the DRV8434A stepper motor driver from Texas Instruments (TI); we therefore recommend careful reading of the DRV8434A datasheet before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to approximately 1.2 A per phase continuously without a heat sink or forced air flow.

Features

4.5 V to 48 V supply voltage range
Can deliver 1.2 A per phase continuously without additional cooling
Built-in regulator (no external logic voltage supply needed)
Can interface directly with 1.8 V, 3.3 V and 5 V systems
Simple step and direction control interface
Eleven different step resolutions: full-step with 100% current, full-step with 70% current, non-circular 1/2-step, 1/2-step, 1/4-step, 1/8-step, 1/16-step, 1/32-step, 1/64-step, 1/128-step, 1/256-step
Adjustable current control lets you set the maximum current output, which lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates
Integrated stall detection with three GPIO pins
Ripple control algorithm (decay mode) that allows tight regulation of current level and increased motor efficiency
Over-temperature thermal shutdown, over-current protection, open load detection ,under-voltage lockout, and charge pump over-voltage protection
Driver IC integrates spread spectrum clocking of its internal oscillator and charge pump for reduced EMI
4-layer, 2 oz copper PCB for improved heat dissipation
Exposed solderable ground pad below the driver IC on the bottom of the PCB
Module size, pinout, and interface match those of our A4988 stepper motor driver carriers in most respects

This product ships with all surface-mount components—including the DRV8434A driver IC—installed as shown in the product picture.
