Quadrature Optical Mouse Replacement Using an Arduino for the Amiga Tank Mouse

Added Atari ST SMD Version Not Tested Arduino is flipped 180° for ST version Use same Amiga Pin definition in Arduino source if using original ST DE9 Connector. * Fixed Wrong Fillplane selected. Corrected it back to GND.

ADNS9800 interface based on code from https://github.com/mrjohnk/ADNS-9800 QUADRATURE interface based on blog from http://danceswithferrets.org/geekblog/?p=742

OpenLaserMouse: common questions

What microcontroller does the OpenLaserMouse use?

The OpenLaserMouse is built around the Arduino_Nano_v3.x, from the AVR/Arduino family.

How big is the OpenLaserMouse PCB?

The OpenLaserMouse measures 56 × 79.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the OpenLaserMouse?

22 components, from 14 distinct parts. The full bill of materials is listed on this page.

Where can I download the OpenLaserMouse design files?

From the chris-jh/OpenLaserMouse repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the OpenLaserMouse design in my own project?

Yes, under the terms of its LGPL-3.0 license, which chris-jh chose for the repository.

Can I test firmware for the OpenLaserMouse 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.
