ScoutMakes DRV5032 Digital Hall Effect Sensor Breakout

Detect magnets with ease using the ScoutMakes DRV5032 Hall Effect Sensor Breakout — a compact, beginner-friendly board built around Texas Instruments' ultra-low-power DRV5032 omnipolar digital Hall effect sensor.

Whether you're building a reed-switch replacement, detecting open/closed states on enclosures, or adding contactless triggering to your next project, this breakout gets you up and running in minutes.

• Ultra-low power — designed for battery-sensitive and always-on applications
• Omnipolar detection — responds to both north and south magnetic poles, so magnet orientation doesn't matter
• JST-PH 3-pin connector — plug-and-play wiring, no soldering required for compatible systems
• CircuitPython ready — works out of the box with CircuitPython-compatible boards
• OSHWA certified — open source hardware you can trust and build upon
• Breadboard friendly — standard 0.1" header pitch for easy prototyping

Works great with Adafruit's line of boards, Raspberry Pi, Arduino, and any microcontroller with a 3.3V or 5V digital input. See the TI DRV5032 product page for the underlying sensor datasheet.

Omnipolar detection: unlike a latch sensor, the DRV5032 responds to a magnetic field from either pole — it doesn't require alternating north and south poles to trigger. This makes it well suited for simple presence/absence sensing (e.g. reed-switch replacement, door/lid open detection, contactless triggering) where you just need to know whether a magnet is nearby, regardless of its orientation.

A note on sensor variant: the DRV5032 comes in several variants that differ in switching threshold and output type, and the specific variant may change between production runs as component availability evolves. Always check the markings on the IC or the product page for the variant shipped with your order, and refer to the TI DRV5032 datasheet for full variant specifications before designing around a specific threshold. The current version (as of July 2026) ships with the DRV5032FBDBZR variant.
