30% in-line keyboard, simple to the ultimate beauty 【ATmega32a】

Ever since I used the 40-key inline keyboard, my obsession with the extremely simple inline keyboard has never stopped. When I saw the 30% keyboards of my predecessors, I was immediately planted.

1. Design and production:

The scheme of using ATmega32a onboard master control is cheap and simple.

Double-board splicing design, a money-saving choice. Bezel-less design, minimized to the limit.

Use my soldering board artifact to solder all the SMT components at one time, see JLC for details.

Although the 9.9 free shipping keycaps are used, the small and exquisite appearance is still very eye-catching, and it is worth traveling with my ipad air.

Positioning plate made of aluminum substrate.

The frame is also saved, and the three-layer board is directly fixed with copper pillars, which seems to have a bit of structural beauty.

The bottom plate made of aluminum substrate has holes for easy programming. Oops, I missed the non-slip rubber pad.

2. Arrangement design:

The most important thing about a keyboard with a small configuration is the configuration. Only the one that suits your own usage habits is the best. Otherwise, the 30-key keyboard can only be a toy, not a tool.

After comparing the use of the two schemes, the arrangement design was finally determined, and the effect is good. For details, see:
