Overview
Neopad is an open-source printed circuit board by ivndbt, from the ivndbt/neopad repository on GitHub, published under the GPL-2.0 licence. It is a 2-layer board of 99.2 × 88.3 mm with 37 parts on 32 nets, routed with 149 tracks and 0 vias.
Its parts include 8 diodes, 3 switches, 2 resistors and 1 IC. It belongs with the keyboards and input boards and the AVR (ATmega, ATtiny) boards of this library.

Overview
Neopad is a little macropad with four switches and two rotary encoders, made by through hole components only. It's designed to use QMK firmware. Actually the number of switches is six, because even the encoder are allowed to click.

The Neopad in the photo above is the first prototype with ultra light case made from biscuits cardboard. In this repo you can find the final revision including:
- fixed reset button pin routing
- fixed positioning of mounting holes
- added breakable PCB for EOTW case
- new shiny artwork

In this repo
Here you can find my KiCad project files and the gerbers I used to manufacture the Neopad. In order to open and modify them you will need to download and add the keebio-components symbols library to the project's path.

Description
- The 2 LEDs rappresent the current layer in binary (max 4 layers rappresented but, accordingly with QMK capabilities, you can program up to 16 layers)
- Total PCB dimensions are 99.22mm x 87.31mm
- Macropad dimensions after build are 99.22mm x 42.86mm

References
I decided to open source this project because I wanted to give back to the amazing mechanical keyboard comunity what was given to me. I owe special mention to the following links that I found extremely useful and that without them I could never achieve this:
- the keyboard designer wiki @ ai03.com for KiCad's tutorial
- Chokkan's YouTube videos for setting up QMK's developing environment
- imchipwood's dumbpad macropad for encoder's routing, LED's behavior, QMK and readme structure

Questions
How big is the Neopad PCB?
It measures 99.2 × 88.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Neopad use?
37 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Neopad KiCad files?
From the ivndbt/neopad repository on GitHub, at the commit this page was made from: the board is Neopad.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Neopad design in my own project?
Its repository publishes it under the GPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
