Overview
Hotreus62 is an open-source printed circuit board by beekeeb, from the beekeeb/hotreus62 repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 270.1 × 112.9 mm with 135 parts on 84 nets, routed with 10,328 tracks and 62 vias.
Its parts include 62 diodes, 62 switches and 1 IC. It belongs with the keyboards and input boards and the AVR (ATmega, ATtiny) boards of this library.
README
README.mdHotreus62 Keyboard
The Hotreus62 Keyboard is a fork of atreus62 keyboard. It supports MX hotswap and Kailh Choc v1 hotswap sockets on the same board, similar to Lily58 Pro. It's great for testing which type of keyswitches feels best for the keyboard. The overall keyboard height is reduced, with the breakout board placing on the top.
More photos can be found at the beekeeb showcase. Pre-soldered keyboard PCBs / DIY kits are available at the beekeeb shop.
Features
- 62 keys: enough keys for having a number row.
- Dual Hotswap Sockets: Support both Kailh Choc (low profile) / MX hotswap sockets on the same board.
- Lower profile: The overall keyboard height is reduced, with the breakout board placing on the top.

Questions
How big is the Hotreus62 PCB?
It measures 270.1 × 112.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hotreus62 use?
135 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 Hotreus62 KiCad files?
From the beekeeb/hotreus62 repository on GitHub, at the commit this page was made from: the board is pcb/hotreus62.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hotreus62 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).
