DIY Bluetooth Mechanical Keyboard Guide

If you have both Bluetooth and wired dual-mode, as well as a mechanical keyboard circuit board, then DIY is possible.

The keyboard and controller are separate, allowing for the choice of cheaper switches to be purchased. Alternatively, if you have spare Cherry switches from an unused 104-key keyboard, those could be utilized, albeit with a bit more hassle.

What's being used here is purchased separately. A 60% keyboard, all keys customizable, multiple layers can be set up, and key configurations can be easily adjusted online.

All keys on the 60% board can be customized.

Switches are mounted one by one.

The positioning plate is installed.

After soldering, keyboard testing shows all keys are functioning properly, and online modification of configurations works flawlessly.

The controller is on the back, with two rows of 16-pin 2.0 headers.

USB 3.1 on both sides.

LEDs for switches are also soldered on. If you don't need red LEDs, white ones will do.

All that's left is the case. Keycaps are purchased separately or preferably from existing stock.

The controller PCB board comes in two models, with NRF52832 Bluetooth modules—one with a larger volume, onboard antenna plus antenna socket, and the other smaller, with onboard antenna, both are usable.

It's compact and offers more key functions.

If needed, you can also get a plastic or CNC aluminum case.
