Design a Custom BoardAbout This Component
Integrated bipolar stepper motor driver with dual H-bridge MOSFETs, microstepping indexer, and on-chip current sensing. Supports 4.5–33V supply, delivers 2.5A full-scale continuous current with 330mΩ on-resistance, and features STEP/DIR logic interface with 1/256 microstepping resolution. Includes smart tune decay technology, thermal shutdown, overcurrent protection, and low-current sleep mode for industrial and consumer applications.
Package: QFN-24 (4×4mm) · 24 pins
Why does this need a breakout?
This 0.5mm pitch QFN is nearly impossible to hand solder and entirely incompatible with breadboards due to hidden pads beneath the package. A breakout board provides accessible headers and pre-soldered connections, letting you prototype with InvenSense motion sensors via I2C or SPI without specialized SMD equipment or rework skills.
