Corne v3 is out thanks to the wonderful Foostan!

Two options (with or without pre-assembly) and three colors (black, white, and purple)

It now features easier to solder LEDs and is panelized. These changes make this board much more friendly to people just getting into the hobby as well as those that are experienced but don’t want to struggle with the LEDs featured in the previous version.

I have also modified the PCB to make it so the holes on the pro micro are slightly larger than before. This makes it so a variety of different sockets can be used on the PCB.

I will be offering partial factory assembled PCBs to make this even easier! All you will have to do is solder the controller (pro micro, elite c, nice!nano, etc…)!

There is also an option to assemble it yourself. Assembling the board is still not a cake walk and it took me about 1-2 hours to assemble.

With an assembled PCB you get a PCB that already has soldered on:

• MX sockets

• LEDs

• TRRS jacks

• diodes

• Reset switches

With the non-assembled PCB, you get all of that stuff but not on already on the PCB

You will still need two micro controllers.

Any of these should work:

• Pro micro - https://keyhive.xyz/shop/pro-micro

• Elite C - https://keyhive.xyz/shop/elite-c

• nice!nano - https://keyhive.xyz/shop/nicenano

These plates are made using PCB material (FR4) and are durable. These will work for the Choc as well as normal MX switches.

Qty 1 gets you:

• two (2) top plates

• two (2) bottom plates

• 10x 8mm standoffs and 20x screws

If you want different screws and standoffs, you can find them in the shop here :)

Two (2) OLED modules
Can be used for:

• Corne

• Helix

• Lily58 pro

Does not come with sockets but does come with the headers pre-soldered

A pro micro alternative with a durable USB-C port and a DFU bootlaoder!

Features:

• Compatible with all Pro Micro-based PCBs

• Mid mount USB-C port that can’t be ripped off

• ATmega32u4 controller

• DFU bootloader

• 6 additional ATmega32u4 pins and USB pins broken out

• On-board reset button (you can still use the reset button on the keyboard PCB if it has one)

• 1.0mm thick PCB for slimmer profile (don’t worry, it’s still very solid and doesn’t flex)

• Comes with two 12-pin headers and one 5-pin header

• Total of 24 I/O pins to work with (6 more than the Pro Micro)

Changes in v4:

• Mid-mount USB-C port (lower profile overall)

• broken-out VBUS pin (above the existing 'PB0' pin) allows the easier use of an external USB port if desired

• Low-profile Reset Switch (shorter than the current one so it lies below the profile of the USB-C port)

This board can be used for just the master half of a split keyboard (corne, lily, helix, etc…) and then a cheaper pro micro on the slave side to save some money!

Detection issues in QMK Toolbox: See info on installing the correct DFU driver using Zadig here: https://docs.qmk.fm/#/faq_build?id=unknown-device-for-dfu-bootloader

Comes in qty of 60

The hotswap Corne requires SMD. The non-hotswap Corne can do either.

Lily58 pro uses SMD best but can use through hole in a pinch.

The UT47 uses through hole.

The Honeycomb doesn’t require any.

One Arduino Pro Micro

It comes in two different variants:

• Micro USB

• USB-C

The USB-C version is slightly longer around the port area, as shown in the diagrams.

Everything else is functionally the same :)

note: Some people have asked if these have a past issue where pins 14/15 are swapped. I tested these and the pins are correct and should not cause any issues

A selection of screws and standoffs. When selecting the length, please consider that a PCB is 1.5mm and acrylic is 3mm.

Screws are stainless steel and pan head.

Standoffs are brass and knurled.

1 qty = 10 screws or 10 standoffs

GB and Extras are all sold out (updated: 05/19/21)
Please sign up for email notifications in order to be notified of when Round 3 goes live later this year

A milled aluminum or PC case for one of the most beloved hobbyist keyboards designed in collaboration between Keyhive (with /u/velvetjaguar) and IMK (https://imkulio.com/ )

There are 4 different options based on survey responses:

• Black Pantone: 433 C

• Space Gray Pantone: 10 U

• Ultraviolet Pantone: 2096 C

• Polycarbonate

Each case will come with:

• Acrylic covers

• Tenting screws (where needed)

• Acrylic bottoms

• Screws and standoffs

• A carrying case

The PCBs and their accessories are also available to be purchase with this group buy at a discounted rate.

I will have partially pre-soldered PCBs available as well as assembly services for those that want a completed board.

Assembly here: https://keyhive.xyz/shop/corne-v3-assembly

If MOQ is not met for the design that you want, we will notify you and allow you to cancel or change your order.
As different quantities are sold, we will be able to lower the price (and refund people). Refer to the chart on this page to find out what the price breaks are.

Production will take about 2-3 months in order to make sure that the quality is good.

More details

——

The IMK Corne is a premium case designed to upgrade, protect and accentuate the beautiful outline of one of Japan's most celebrated custom split keyboard: the Corne by foostan.

Unibody Design

The plate and protective side walls are machined from a single block of aircraft grade aluminum. Giving you a case that is both light enough for travel and strong enough to prevent flex.

Open Bottom

The case features an open bottom design closed using the Corne's acrylic bottom plate. Allowing the under-glow LEDs to shine through while also giving you a window to inspect the beautiful PCB and components inside.

Flexible Tenting

The tenting holes has been carefully placed to allow the case to lay flat for travel when the tenting legs are removed.

There are four M3 sized tenting holes that you can use to adjust both the tent and tilt of each side of the keyboard to your liking.

You can use the black tenting legs that comes with the IMK Corne, or simply replace or join your choice of readily available M3 standoffs and screws for unlimited angles and style.
