40%Keyboard-V2

Overview

I previously open sourced a mechanical keyboard with a 40% Planck configuration , but after using it for a while, I found that I was not used to it, so I made this version.

Type-C interface, Kaihua hot-swappable axis base, upper light position RGB axis light, supports 5-pin axis, supports PCB satellite axis, QMK firmware and has a via version.

I made a 32U4 PCB, appropriated the main control on it , and then installed the aluminum case I bought before on this keyboard.

When I was drawing the board, I drew the 32U2 version by the way, but 32U2 seems to be not cheap now, but I still have two pieces in stock.

When typing the board, I don’t know why the Enter key was deflected about two millimeters to the right. This has been corrected.

I don’t know if there is any cheap and easy-to-use master controller that supports qmk. Can anyone recommend it? If I have time, I might consider drawing a few more different master controllers.

I have considered 3D printing a casing, but I don’t know how to draw. I installed a software before and wanted to learn it, but I found that my laptop couldn’t carry it...

Although the pcb satellite axis is supported, I personally recommend the positioning board satellite axis, because the steel wire of the satellite axis in the shift position will block the screws and make the screws difficult to tighten.

The default firmware of this keyboard also comes with layer indicators and caps lock indicators. Here is my keymap.

This is the default layer of the keyboard. The keyboard is on this layer when there is no other operation.

This is the number and punctuation layer.

This is the F area and light settings layer.

The fourth layer is the same as the second layer, except that pressing Enter changes to return to the default layer. The fourth layer is mainly used to input numbers continuously.

By the way, here are two photos of PCBA

I don’t know if there is anything else I haven’t thought of, so I’ll just write it here.
