Good to know

nice!view, OLED or no displays?+

nice!view is a low-power memory LCD that suits a wireless board: it stays readable in daylight and barely touches the battery. It runs on ZMK only. The OLED version is $20 less and works with QMK, ZMK or RMK. Without displays it is $5 less again, with the same firmware choice.

Which firmware should I choose?+

QMK is wired: the halves link with a USB-C to USB-C cable you can plug and unplug safely (no TRRS shorting), and you remap with Vial. ZMK and RMK are wireless: Bluetooth or USB-C to the computer, with the halves talking wirelessly. ZMK remaps with ZMK Studio, RMK with Vial.

Kit or assembled — which should I pick?+

No soldering either way. The kit arrives soldered and assembled, with Poron plate foam and bottom foam already fitted — just press in your own Choc V2 switches and keycaps (no switches? add a box of 70 Kailh switches when you order). The assembled board comes with the Kailh switches you pick and LAK keycaps fitted, tested and ready to type on, for $50 more; KLP nylon-printed keycaps add another $30.

Can I use regular MX switches?+

No. This CORNE is built for Kailh Choc V2 low-profile switches.

How much is shipping?+

Free on orders over $99, so every CORNE ships free. Each order is prepared and shipped within 10–15 business days. Orders to Europe, the US, Japan and Korea ship duty-paid: part of the import tax is added at checkout (Europe 12%; US, Japan, Korea 5%), we cover the rest, and there's nothing more to pay on delivery.
