PMW3610 Breakout Board

What is it?

A ready-to-use motion tracking breakout board that's perfect for building custom computer mice, trackballs, or adding motion sensing to any project. It uses the PMW3610 sensor (the energy-efficient cousin of sensors found in gaming mice) with all the tricky electronics already handled.

Documentation & Examples

This breakout board is used in my ergonomic keyboard build - you can use it as a reference when integrating the PMW3610 into your own projects.

Why did you make it?

I built a custom keyboard with integrated trackball, but couldn't find an optical sensor for sale that fit my requirements. I needed support in ZMK, and low energy requirement since my keyboard was wireless. This PMW3610 fit the requirements!

Whether you're crafting a unique trackball keyboard, building a custom mouse, or adding motion sensing to a battery-powered project, you need something reliable and power-efficient. This board makes it simple to add high-quality tracking without the headaches.
