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
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!
You can use it as a reference when integrating the PMW3610 into your own projects.
- Complete Project Repository - Working ZMK firmware and build instructions
- PMW3610 Wiring Diagram - Pin connections and setup guide
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.
What makes it special?
- Widely supported sensor has great driver support on many platforms.
- Super low power consumption - perfect for battery-powered projects
- Ideal for custom mice, trackballs, and keyboard builds
- Clear labels on all pins - no confusing wiring diagrams needed
- Each board is hand-tested before shipping from Arizona, United States
Specifications
- Sensor: PMW3610DM optical motion sensor
