DRV8434x Stepper Motor Driver Carriers

These breakout boards for TI’s DRV8434x bipolar stepper motor drivers feature adjustable current limiting and 11 microstep resolutions (down to 1/256-step). They operate from 4.5 V to 48 V and can deliver up to approximately 1.2 A continuous per phase without a heat sink or other additional cooling (2 A peak). Several versions are available with options like integrated stall detection and SPI control; the following table compares each carrier’s the key features:

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 continuous per phase without a heat sink or forced air flow (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.

Quantity:

This version of our DRV8434A Stepper Motor Driver Carrier ships with male header pins installed, so no soldering is required to use it with an appropriate 16-pin socket or solderless breadboard. Please see the DRV8434A Stepper Motor Driver Carrier product page for more information about the driver.

Brand: Pololu supply outlook
Status: Rationed (Active and Preferred) 
RoHS 3 compliant
Out of stock.
Quantity:

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.

Brand: Pololu supply outlook
Status: Rationed (Active and Preferred) 
RoHS 3 compliant
Out of stock.
Quantity:

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 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).
