This keyboard is inspired by luantty2's Candy BLE (https://github.com/luantty2/nRF52840-instruction). When I first saw that I was like "Beautiful! Marvelous!" but that would be nice to make that in 65%. So With no basic knowledge of electronic I brave myself to learn Kicad with the guide of https://wiki.ai03.com/books/pcb-design/page/pcb-guide-part-1---preparations. Basically this is just an nrfmicro 1.4 by Joric embedded in PCB. I also learn some basic Fusion 360 to make a keyboard case and plate.

When I finish designing this, I realize I am not he first one to design this, there is someone in zfrontier forum already done it, it is called Rainbow65, check it out https://www.zfrontier.com/app/flow/e1rpMAd9Nz75. and there is someone planning an IC for similar layout and feature.

Anyway here is the photos of me making this board https://imgur.com/gallery/9tkokVy

Case

All the case is all 3d printed, except the ergo version have acrylic version case. The case have 3 part, top, middle and bottom. the top and bottom using PLA with 20% infill, while the middle use transparent PLA with 100% infill(to diffuse the underglow RGB) I only know some basic 3d knowledge, so if my case is not to your liking you can design your own case and make a PR or keep it to yourself. Here some rendered Image from fusion 360.

I am too lazy while designing this one, so I only design ANSI layout case. The plate is integrated to the case, so if you want different layout you want to make another case.
