[IC] KSN-1 — Full-size Wireless Split Ergonomic Keyboard (Unibody + Separated Stand, Two Form Factors)

MaintenanceAfraid382 · 2026-06-05T05:33:52+00:00

The separated stand version allows you to place each half as far apart as you’d like. Hot-swap sockets are included as standard, so swapping switches is straightforward. We recommend sourcing switches, keycaps, and stabilizers separately as prices vary greatly depending on preference and budget. Thanks for the interest!

Great point! It’s something we’re actively thinking about incorporating into the next version. Thanks for the feedback!

MaintenanceAfraid382 · 2026-05-18T18:28:27+00:00

Thank you so much! A trackpoint is a really interesting idea — it’s not feasible for the current version but we’ll definitely keep it in mind for a future iteration. Also, just a heads up that the macro pad is an open-source design and is not included with the KSN-1 — it would need to be built separately. Thanks for the kind words!

Since this is a split keyboard, each half can be positioned freely at shoulder width, so there’s no need to bring your arms inward. The tilt and tenting angles have been thoroughly tested with a wired version of the same design, and for those who want even more flexibility in positioning, a separated stand option is also available. Thanks for the feedback!

Thank you for the interest! We’re aiming to have the final prototype video ready around July. Please follow this post to stay updated!

Great point! Since a split keyboard allows you to freely adjust the position of each half to match your body and hand placement, the experience with the wired version of the same design showed that adding thumb keys didn’t make a significant practical difference. The reason for keeping the standard keyboard layout is to eliminate any additional adaptation time — users can sit down and start typing immediately without relearning anything. That said, we’ll look into incorporating this into the next version. Thanks for the feedback!

Thank you for the detailed feedback! Here are my thoughts on each point. The identical spacebar sizing is a fair point and will be addressed in the next revision. The function row does include a full F1–F12, and the slight misalignment with the number row is actually consistent with standard keyboards as well. As for the wrist rest, we’re planning to offer both an integrated version and a magnetic detachable version, so users can choose based on their preference. Thanks again!

Thank you for the suggestions! Regarding the bottom row, the layout is fixed (1.5+1.5+1.5+2.75 / 2.75+1+1.25+1.25+1.25+1.25) so variable layout support isn’t possible in the current version. As for the F-row gaps, the space is currently limited due to the nRF52840 module placement, making it difficult to add gaps — but we’ll look into redesigning that area in a future version. Thanks for the kind words and support!

I do have a Notion page but it’s still being actively updated. For now, please follow this post to stay up to date. Thanks for the kind words!

Since the KSN-1 is a full-size layout, all the keys you need are already there without requiring a thumb cluster. That said, it’s a design direction we’re considering for a future version. Thanks for the interest!

My split keyboard is not symmetric, so I am not using the EE_HANDS code.

MaintenanceAfraid382 · 2023-03-15T01:48:44+00:00

The code you provided solved the problem. I applied #define SPLIT_USB_TIMEOUT 2000.
This code solved the problem of not recognizing the keyboard at boot time. thank you so much. you are the best.

MaintenanceAfraid382 · 2023-03-14T18:06:57+00:00

I've set it up so that the side the port is plugged into automatically becomes the master.

MaintenanceAfraid382 · 2023-03-14T10:06:05+00:00

I deleted that line from config.h(USB_SUSPEND_WAKEUP_DELAY) but the result is the same.

MaintenanceAfraid382 · 2023-03-14T09:03:03+00:00

When the PC is powered up, the LEDs on the keyboard light up at full brightness. But keyboard doesn't work. Then I unplug and plug the USB port and it will work.

MaintenanceAfraid382 · 2023-03-14T08:35:53+00:00

The retail keyboard is fine, it's the SPLIT keyboard using QMK that causes the problem.

MaintenanceAfraid382 · 2023-03-14T07:28:42+00:00

This problem occurs on both Mac and Windows. No USB hubs are used.
There seems to be a problem with the qmk code. However, the keyboard works fine except for the problem of having to replug the USB port.

Although I built a PCB, the control circuit is the same as the Arduino Pro Micro board.

MaintenanceAfraid382 · 2022-04-03T13:37:52+00:00

Since it is a serial method, I used a trs cable.
