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

OpenLaserMouseTHT: common questions

What microcontroller does the OpenLaserMouseTHT use?

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

How big is the OpenLaserMouseTHT PCB?

The OpenLaserMouseTHT measures 56 × 84 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the OpenLaserMouseTHT?

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

Where can I download the OpenLaserMouseTHT 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 OpenLaserMouseTHT 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 OpenLaserMouseTHT 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.
