Overview
Keyboard is an open-source printed circuit board by dannyjim-ml, from the dannyjim-ml/idb60-ReplacementPCB repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 282.6 × 104.2 mm with 167 parts on 109 nets, routed with 1,071 tracks and 69 vias.
It is built around the ATMEGA32U4-MU, SRV05-4 and SK6812MINI-E. Its parts include 65 diodes, 65 switches, 11 capacitors, 7 resistors and 2 ICs. It belongs with the keyboards and input boards and the AVR (ATmega, ATtiny) boards of this library.

README
README.mdAftermarket idb60 pcb
Introduction
This aftermarket pcb for the idb60 is plain and simple - an MX replacement pcb with USB-C, ESD protection, and a new bottom row option. This PCB has been produced previously by JLCPCB, and tested to fit and work with the original idb60 case.
The current implementation of the RGB caps lock indicator is nonfunctional and should be either removed or updated prior to future production. The original intended RGB LED was the SK6812MINI-E. The RGB indicator should also be slightly relocated further south since currently, the switch covers a majority of it up.
Features
- USB-C
- ESD Protection
- VIAL Support
- (theoretical) RGB Indicator
Supported layouts
Contributors
- Pngu, for creating a wonderful board.
- Ludwig Van Keebhoven, for designing an open source ALPS replacement PCB that helped in the design of this pcb.

Questions
How big is the Keyboard PCB?
It measures 282.6 × 104.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Keyboard use?
167 parts, built around the ATMEGA32U4-MU, SRV05-4 and SK6812MINI-E. 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 Keyboard KiCad files?
From the dannyjim-ml/idb60-ReplacementPCB repository on GitHub, at the commit this page was made from: the board is aftermarket_idb60/keyboard.kicad_pcb and its schematic aftermarket_idb60/Matrix.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Keyboard design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
