Overview
PcbProject2 is an open-source printed circuit board by KrishPatil512, from the KrishPatil512/MacroPad repository on GitHub, published under the MIT licence. It is a 2-layer board of 62 × 49 mm with 5 parts on 14 nets, routed with 33 tracks and 0 vias.
Its parts include 3 switches and 1 IC. It belongs with the keyboards and input boards and the SAM D and SAM boards of this library.
README
readme.mdMacroKeyboard Project
A simple custom macro keyboard built to trigger shortcuts, automate tasks, and speed up everyday workflows.
This project is a compact macro keyboard using a microcontroller (like ESP32) and programmable buttons to send custom key inputs to a computer. It can be used for productivity, gaming, or creative workflows.
Features Custom programmable keys Supports keyboard shortcuts/macros Compact and portable design Easy to modify and expand Can be used with different layouts
Hardware Used ESP32 / microcontroller Mechanical switches / buttons PCB OLED .96 in screen Optional: enclosure (3D printed or case) How It Works
Each button is mapped to a specific function. When pressed, the microcontroller sends a signal to the computer (via USB) that acts like a keyboard input.
Example:
Button 1 → Copy (Ctrl + C) Button 2 → Paste (Ctrl + V) Button 3 → Open app Setup Clone the repository Upload code to the microcontroller Connect via USB Customize key mappings in code Project Structure /code → firmware and logic /pcb → PCB design files /cad → enclosure / case design /bom → bill of materials Future Improvements Rotary encoder support OLED display Wireless (Bluetooth) control Custom software interface

Questions
How big is the PcbProject2 PCB?
It measures 62 × 49 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PcbProject2 use?
5 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 PcbProject2 KiCad files?
From the KrishPatil512/MacroPad repository on GitHub, at the commit this page was made from: the board is pcb/pcbProject2.kicad_pcb and its schematic pcb/pcbProject2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PcbProject2 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
