Releases: foostan/crkbd
v4.1
Fix GND/VCC for mini version
Issue: If cutting the end rows for the mini, the PCB will become unusable.
Fix TRRS connector
Issue: The current TRRS connector ST-0277D00-052-142 is not in stock and there are no compatible parts.
Alternative parts (You can choose any of them)
- PJ-398A-5A: Very similar parts to current parts. It does not need to be modified on the case side but the circuit and firmware need to be modified to support TRS and it's not available at jlcpcb.
- PJ-399B-6A: Very similar parts to current parts. The connector tip is long and needs to be modified on the case side and the circuit and firmware need to be modified to support TRS. -> to be default for jlcpcb files.
- SJ-3501-SMT-TR: Compatible with PJ-399B-6A but the circuit and firmware need to be modified to support TRS.
v4.0
Summary
It details the design changes in the latest version of the Corne Keyboard. I intentionally abandoned backward compatibility to achieve technological advancement and design updates. Changes include fine-tuning the key pitch, MCU alteration, TRRS jack and LED design improvements, the addition of expansion options, and the introduction of a new dedicated case.

Major Design Changes
Changes from v3
Abandonment of Backward Compatibility
The new version deliberately abandons backward compatibility with past models to enhance design freedom and aim for technological progress and design updates. This decision, while difficult due to its incompatibility with third-party cases, was deemed necessary for future development.
Major Design Changes
- Change in Key Pitch
- Departure from ProMicro
- Change in TRRS Jack Parts
- Abolition of Underground LEDs
In the new version, the key pitch has been adjusted from 19mm to 19.05mm to align with the dimensions of typical keyboards. Initially, the Corne design deviated from standard dimensions due to a lack of knowledge, but I have finally been able to correct this. Furthermore, replacing ProMicro with direct implementation of RP2040 on the PCB has improved the appearance and functionality of the product. The change in TRRS jack parts has also simplified the overall look of the keyboard. Additionally, the abolition of Underground (downward-facing) LEDs has been implemented for cost reduction and simplification.
Expansion
The space created by the removal of ProMicro has led to enhanced expandability for users. Continuous use of OLED displays, along with the possibility to add up to two expansion switches or rotary encoders, is now available. This allows users to customize their keyboards according to their needs, creating more unique and functional keyboards.
Dedicated Case
With advancements in 3D printing services, the new version also focuses on the design of a dedicated case. This case has a simple design and can be manufactured at a low cost. Users can easily customize the case to create their unique keyboards. These designs are published as open source, serving as references to foster creativity in the community and meet diverse needs.
Corne's Concept and Gratitude to the Community
Finally, the concept of Corne is to share the joy of creating keyboards and the possibility of designing them oneself, aiming to provide a foothold for users to design their original keyboards. I am deeply grateful that this project has continued much longer than imagined and has received support from many people. It is a great pleasure as the creator to see various individuals take an interest in this keyboard, assemble it themselves, and create new designs.
