HID projects

HID (Human Interface Device) projects; Keyboards, trackballs, controllers of all sorts.

This repo is for the HID projects I have been working on and are making public for anyone to use, replicate, innovate, and otherwise utilize to their liking. If you make any new design changes/innovations, I would love to see them and potentially add them to the repository!

Alpha29 pmw3360: common questions

What microcontroller does the Alpha29 pmw3360 use?

The Alpha29 pmw3360 is built around the ATMEGA32U4-AU, from the AVR/Arduino family.

How big is the Alpha29 pmw3360 PCB?

The Alpha29 pmw3360 measures 301 × 77 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Alpha29 pmw3360?

14 components, from 13 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 Alpha29 pmw3360 design files?

From the Skycode22/HIDs repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Alpha29 pmw3360 design in my own project?

The repository has no license, so all rights stay with Skycode22. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Alpha29 pmw3360 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.
