[Spark Project] The most beggar 17+4+ touch mechanical keyboard PRO

Introduction: The orthodox sequel to the most beggar's touch numeric keyboard, this time the code will be open sourced for the first time.
Don't say that you, the author, don't follow martial ethics. I just created your old project and you updated it.
The functionality and practicality completely surpass the previous version. Moreover, it was published one and a half years apart

Regarding the content, the following description is not all of this keyboard. There is also a sister project "The Most Beggar 68+4 Mechanical Keyboard PRO". It is better to use the two together.
Coincidentally, the two competitions are now being held at the same time, so the two projects are pitched on different tracks. In order not to repeat the content, the emphasis is different.

Preface
To be honest, the most popular among my open source projects is the small keyboard project , because of its low cost and unique touch bar functions, many people do it.
Of course, the high number of views may also be related to the keyboard macro automatically opening the open source URL. The original intention is to facilitate everyone to browse the instructions and emphasize the open source nature of the project. There is no malicious intent to increase the number of views!
While interacting with readers, I saw all kinds of people. Some of them regarded welding as much fun as building a Gundam. They even thought that my project required less welding and asked me to make it more difficult.
Some people don't read the instructions and hope that the layout will omit the prominent part. After explaining that this is a touch bar, I sighed, "The function is so NB, only for this price."
I have also seen students who are not majoring in electricity buy a soldering iron for the first time for this project. Ask me to recommend soldering tools.
There was even an uncle with a baby who took out a soldering iron that had been sealed for a long time and started soldering. (It’s true that seniority is called that, but people who play with electronics are not convinced by their seniority. They may think that picking up a soldering iron will bring them back to their school days.

#十三级电竞# The most beggar 68+4 mechanical keyboard PRO

Introduction: An upgrade based on my old project "The Most Beggar 61+3 Mechanical Keyboard".
The layout was modified, the HUB planned to be added from the beginning was added, the keyboard backlight was changed to RGB, and OpenRGB was connected.

If the competition ends, please jump to the open source platform to view the latest version. When the competition ends, the score locking project will be carried out. This layout will then become uneditable. The GaiZhongGai-Keyboard-68+4PRO - EasyEDA open source hardware lab (oshwlab.com) also has an English version for communicating with foreign friends. Regarding the content, the following description is not all of this keyboard. There is also a sister project "The Most Beggar 17+4+ Touch Mechanical Keyboard PRO", it is better to use the two together. Coincidentally, the two competitions are now being held at the same time, so the two projects are pitched on different tracks. In order not to repeat the content, the emphasis is different. Preface Many readers who are not in the computer installation circle may not understand the meaning of this beggar's beggar. This word is more commonly used on computer motherboard graphics cards. It refers to the beggar’s edition among beggars’ editions, the low-profile among low-profile, the shrinkage among shrinkage, which is homophonic to the former CCTV advertisement. And I’m not using it as a project name for sales promotion, so there’s no problem. The benefits of low configuration are obvious, that is, the cost is low, and students love it most. We all have experienced spending money on electronics, but as teachers, I hope you will not cut back or even skip meals when budgeting for living expenses. You can find a classmate AA, or use extra PCB assembly to hang idle fish to recover health (investment is risky!!!), but remember to comply with the open source agreement. Here is a comparison table of commonly used microcontroller configurations with QMK solutions: model STM32F103C8T6GD32F103C8T6ATMEGA32U4-AUCH551 G Lichuang number C8734C77994C44854C108958 single price (June 24, 2022) ￥42.58￥14.35￥129.92￥ 2.69 package LQFP-48LQFP-48QFP-44SOP-16I/O number 37372612.5 (RST pin can only be read, when half) digits 32-Bit32-Bit8-Bit8-Bit core ARM® Cortex®-M3ARM® Cortex®-M3AVRC51ROM64kB64kB32kB10kBRAM20kB20kB2.5kB0.75kBEEPROM None (but can be simulated with FLASH) None (but can be simulated with FLASH) Can use FLASH simulation) 1kB128B comparison shows that the configuration difference is not big, the main reason is that there is no ecology. When the keyboard was first released as open source, I planned to open source the code, but I felt that it was not popular enough and I was afraid that someone would use it for profit and delete the original author information. However, the "core shortage" caused the price of the above microcontrollers to rise, and the popularity of my project also increased. Moreover, there is also the spiritual and material support of loyal fans, who help communicate with Xianyu sellers to add open source tags, and reward the author with a fixed amount after the sales proceeds. With such support, can you update diligently? Thank you for your support along the way~ 1. The project function introduction is based on the upgrade of my old project "The Most Beggar 61+3 Mechanical Keyboard". To satisfy my original need for a keyboard with a hub, since there was no room for a third USB socket, I placed an SD card reader under the space. The configuration has been modified, the keyboard backlight has been changed to RGB, and OpenRGB has been connected. And Chinese support has been added to the project. With the poor peripherals of CH551G, a lot of optimizations have been made to meet the strict timing requirements of WS2812. Normal state
