This breakout board for TI’s DRV8434 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 continuous per phase without a heat sink or forced air flow (2 A peak). The driver has inputs for setting the decay mode and includes two smart tune current regulation modes that help you achieve smooth steps without manual tuning. 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.

4.5 V to 48 V supply voltage range (note: these are not recommended for use with 48V batteries, which can be well above nominal when fully charged)
Can deliver up to 1.2 A continuous per phase without additional cooling (2 A peak)
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
Six decay modes including two smart tune current regulation modes that help you achieve smooth steps without manual tuning
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

Included hardware

The DRV8434 stepper motor driver carrier ships with one 1×16-pin breakaway 0.1? male header. The headers can be soldered in for use with solderless breadboards or 0.1? female connectors. You can also solder your motor leads and other connections directly to the board. For a version of this carrier with header pins already installed, see item PO3763.

Dimensions

Size: 0.6? × 0.8?
Weight: 1.3 g. Without included optional headers.

General specifications

Minimum operating voltage: 4.5 V. Inputs below 6 V reduce the maximum settable current limit. With 4.5 V in the maximum settable limit is 1.75 A.
Maximum operating voltage: 48 V. Not intended for use with 48V batteries, which can be well above nominal when fully charged.
Continuous current per phase: 1.2 A. Without a heat sink or forced air flow.
Maximum current per phase: 2 A. With sufficient additional cooling.
Minimum logic voltage: 1.8 V. Logic high threshold varies for two-state, tri-state, and quad-state pins.
Maximum logic voltage: 5.5 V. Absolute maximum voltage on any input is 5.75 V.
Microstep resolutions: full with 100% current, full with 70% current, non-circular 1/2, 1/2, 1/4, 1/8, 1/16, 1/32, 1/64, 1/128, 1/256
