About the Mouse PCB

Mouse is an open source AVR/Arduino PCB design by biomurph, published on GitHub under the MIT license. It is a 2-layer board measuring 50 × 90 mm, with 47 components from 30 distinct parts.

Its main chip is the ATMEGA32U4RC-AU, from the AVR/Arduino family. Other key parts include the ADNS2610PTH and ENCODER-QUADRATURE. By type, the board carries 12 capacitors, 9 resistors, 8 connectors, 4 switches, 4 diodes and 3 ICs.

It belongs with the sensors designs in this gallery.

From the project

Repository for Open Source Mouse Firmware and Hardware

If you are interested in modifying the design files to bring this project up to date, the one place that I have found that still sells these kinds of optical mouse sensors is a company called PixArt that has a variety of sensors to choose from. One of my goals is to do just that, so watch this repo if you want to be among the first to know when I have a working prototype.

The KiCad project lives in the biomurph/Mouse repository on GitHub; these links point at the commit this page was built from.

Mouse: common questions

What microcontroller does the Mouse use?

The Mouse is built around the ATMEGA32U4RC-AU, from the AVR/Arduino family.

How big is the Mouse PCB?

The Mouse measures 50 × 90 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mouse?

47 components, from 30 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Mouse design files?

From the biomurph/Mouse repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Mouse design in my own project?

Yes, under the terms of its MIT license, which biomurph chose for the repository.

Can I test firmware for the Mouse without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
