Triple-Mode Gaming Keyboard

The Corn Electronics 87-key mechanical keyboard connects via Bluetooth 5.0, 2.4 GHz wireless or USB-C wired modes. It uses Cherry MX Red linear switches and PBT keycaps in a grey finish. The compact layout suits gamers and mobile users who want a responsive board for PC, laptop or tablet without a numeric keypad.

Hot-Swappable Switch Installation

Switches are hot-swappable, so you can replace them without soldering by pulling the old switch out and pressing a new one in. Align the pins carefully to avoid bending them. The board runs on four AAA batteries, which are not included; forgetting to insert them is the most common reason the keyboard appears dead on arrival.

Pre-Purchase Compatibility Check

Verify that your device supports Bluetooth 5.0 or has a free USB-A port for the 2.4 GHz dongle. The keyboard pairs as "Varmilo VD-1" on the first Bluetooth channel, with VD-2 and VD-3 available on F2 and F3. Confirm you can supply four AAA cells for wireless use, as no rechargeable pack is built in.

Questions about this item

How do I know the keyboard is on and paired after setup?

Hold Fn+Insert for three seconds; F1–F4 lights flash or F4 stays on to show power. F1 lit means Bluetooth channel 1 is connected, F4 lit means the 2.4 GHz dongle is active.

What comes in the box and what must I supply?

The keyboard itself is included; 4 AAA batteries for wireless power are not included and must be purchased separately.

Which version suits a user who wants hot-swappable Cherry MX Red switches and PBT keycaps in a compact layout?

This single model delivers all three: 87 keys, hot-swappable Cherry MX Red switches and PBT keycaps in a grey TKL form factor.
