Cherish-75 is a customized mechanical keyboard featuring a Gasket structure, with its PCB already verified through prototyping.

Qmk and via support,[Source Code](https://github.com/qmk/qmk_firmware/tree/master/keyboards/soda/cherish)

## Features

* License: MIT – Free to use and modify.

* Controller: STM32F072CBT6, with a separate Type-C subboard ensuring soft elasticity.

* PCB: Slotted PCB design with optional solder mask opening (gold plating available). See [Link](https://oshwhub.com/caiyahoho/Cherish-75) for the LCSC project.

* Layout: 75% size, Fang tooth arrangement.

* Switch: Supports both soldering and hot-swappable switches.

* RGB: Features an RGB SMD LED beneath the Caps Lock key.

* Firmware: Compatible with QMK & VIA. Refer to the [fireware] directory for details.

* Case: 3D printed design with magnetic top and bottom covers. Check the [3d-model] directory for designs.

## Instructions

Magnet specifications: Diameter 3mm x thickness 2mm, available on TaoBao

Circuit board: 5 pieces, JLCPCB, 110 yuan

Components: Shaft support, chip, around 50 yuan, available on the JLCPCB online store

Positioning board: With or without slots, recommended material is FR4 or POM, 30-40 yuan per sheet, recommended store on TaoBao is "Proud Cat" for high accuracy

Place 2mm thick P foam on each pin of the PCB

3D print the casing, options include JLCPCB's 3D Monkey or Future Factory, 3D Monkey has higher accuracy but slightly higher price, the upper and lower casing would be around 150-200 yuan.
