DRV8434S SPI Stepper Motor Driver Carrier, Potentiometer for Max. Current Limit
£6.54 ex VAT
This product is a carrier board or breakout board for the DRV8434S stepper motor driver from Texas Instruments (TI); we therefore recommend careful reading of the DRV8434S datasheet before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to approximately 1.2 A continuous per phase without a heat sink or forced air flow
- 4.5 V to 48 V supply voltage range
- Can deliver up to 1.2 A continuous per phase without additional cooling (2 A peak)
- Can interface directly with 1.8 V, 3.3 V, and 5 V systems
- Highly configurable through SPI interface
- Optional STEP/DIR control pins (stepping can also be controlled through SPI interface alone)
- 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
- Eight configurable decay modes, including smart tune dynamic decay and ripple control modes
- Two current limit control options available, each with two header pin assembly options, making four versions in all:
-
Potentiometer for Max. Current Limit: an on-board potentiometer sets the maximum current limit up to 2 A, and the actual current limit can be scaled down through SPI
- with header pins included but not soldered
- with header pins soldered
-
2A Max. Current Limit: the maximum current limit is fixed at 2A and the actual current limit is set solely through SPI in increments of 125 mA
- with header pins included but not soldered
- with header pins soldered
-
Potentiometer for Max. Current Limit: an on-board potentiometer sets the maximum current limit up to 2 A, and the actual current limit can be scaled down through SPI
- Integrated stall detection
- 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

Arduino library for the Pololu DRV8434S SPI stepper motor driver carrier
This is a library for Arduino that helps interface with a DRV8434S stepper motor driver. It uses the Arduino SPI library to communicate with the SPI interface (nSCS, SCLK, SDI, and SDO) of the DRV8434S.
