Overview
Morizon choc is an open-source printed circuit board by skarrmann, from the skarrmann/morizon repository on GitHub, published under the MIT licence. It is a 2-layer board of 252 × 85 mm with 145 parts on 94 nets, routed with 663 tracks and 12 vias.
Its parts include 66 diodes, 66 switches and 1 IC. It belongs with the keyboards and input boards and the AVR (ATmega, ATtiny) boards of this library.
README
README.mdMorizon Keyboard
Morizon is a 5-row version of the Horizon keyboard.
This project is a direct modification of the Horizon project. The schematic and PCBs have been modified to support this 5-row layout.
As with Horizon, two separate PCB designs are available in the gerbers folder: one for MX switches (19mm x 19mm spacing), and one for Choc switches (18mm x 17mm spacing).
Please refer to the Horizon keyboard repository for project documentation. Only Morizon-specific details are noted below!

Bill of materials
Same as the Horizon keyboard BOM, but you will also need:
- Morizon PCBs (instead of Horizon PCBs)
- 14 more keyswitches
- 14 more keycaps
- 14 more 1N4148 SOD-123 diodes
- 1 more M2 6mm screw
- 1 more M2 nut
Revision History
- Rev1 (2022-02-05)
- PCB: Create MX and Choc boards with bottom and top plates (based on Horizon).
- Schematic: Wire as 66 key 10x7 matrix.
- Rev1.1 (2022-03-21)
- PCB, Schematic: No physical changes. Files upgraded to KiCad 6, and Gerber files regenerated using Horizon Board Producer 2.3.
- Rev1.2 (2023-11-09)
- PCB, Schematic: No physical changes. Files upgraded to KiCad 7, and Gerber files regenerated using Horizon Board Producer 2.4.

Questions
How big is the Morizon choc PCB?
It measures 252 × 85 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Morizon choc use?
145 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 Morizon choc KiCad files?
From the skarrmann/morizon repository on GitHub, at the commit this page was made from: the board is kicad/choc/morizon-choc.kicad_pcb and its schematic kicad/choc/morizon-choc.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Morizon choc 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).
