说明：板子和OLED屏幕均来自risym淘宝店，由于资料较为繁杂，且板子和OLED屏幕的脚并不对应，需要重新接线，为防止自己忘记，写一个记录。想要学习使用7脚OLED的同学可以快速看懂。

现在的人们每天在电脑前花费大约10个小时; 扭动鼠标，点击和敲击键盘，这些东西已成为我们生活中不可分割的一部分。现在给大家介绍一款DIY自制的OLED显示屏无线机械键盘。
机械键盘3D
无线机械键盘PCB&电路图（AD打开）
Specs:
True wireless keyboard
No wires allowed. Communication and charging everything is done wirelessly.
Fully Portable
Due to the wire-free policy, making it portable is as easy as it sounds.
62 X Cherry MX mechanical switches
Yes, no discussion about this. Cherry MX or no keyboard at all. Did I say it has to be Cherry MX Blue as well?
68 X RGB LED backlight
An array of WS2812b black version embedded on the board. Who could've thought maker's favorite RGB led is underneath a keyboard.
2 X Thumb Analog Joystick
On the left side simulates the mouse movement while the right side trigger the arrow keys.
Security (RFID/NFC)
In complement with things like NFC Ring, or smartphones NFC, having a secure on-board password activator doesn't sound impossible.
Internet of thing thingy
To enable independent internet access, ESP8266 Wifi dongle was added on-board.
Local wireless communication (Bluetooth 4.0 & LORA)
Talks wireless-ly with local networks that you've setup is now possible with Bluetooth and growingly popular LORA network on-the-go.
Bluetooth HID
Bluefruit HID link from adafruit is used to enable pure wireless system. This significantly save development time.
OLED Display
128x32 pixel OLED display embedded for some indications and notifications on board.
Local Storage
Micro SD card should be able to handle the demand in here.
Microcontroller
For the first iteration, old School ATMEGA2560 is used. Together with atmega328p a co-controller for the WS2812b LED.
