## Description

**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](https://github.com/trentrand/ergonomic-keyboard) - you can use it as a reference when integrating the PMW3610 into your own projects.

- **[PMW3610 Wiring Diagram](https://github.com/trentrand/ergonomic-keyboard/blob/main/PMW3610%20Instructions.pdf)** - Pin connections and setup guide
- **[Complete Project Repository](https://github.com/trentrand/ergonomic-keyboard)** - Working ZMK firmware and build instructions

**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](https://zmk.dev/), 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.

**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
- Supply voltage: 3.3V
- Current consumption: Ultra-low power (ideal for battery projects)
- Communication: SPI interface
- Motion detection: Up to 1000 CPI
- Board dimensions: 23.5mm x 31.5mm
