## Description
The ErgoSplit50 is a 50% split keyboard which means that the keyboard is in two half's which is better for ergonomics than a "normal" keyboard. A 50% Keyboard is smaller compared to a normal 100% keyboard with function and number keys as well as a num keys.
The Keyboard has a ortho linear key layout which is more ergonomic than the staggered key layout (normal layout).
___
Here you can see both half of the keyboard built using [Keyboard Layout Editor](http://www.keyboard-layout-editor.com/#/gists/dc776eb6e80d4ed39cddeabd265ff729)
___
This keyboard layout is better for ergonomics as it accommodates the different sizes of your fingers.

## Firmware
The firmware i used is called [QMK](https://docs.qmk.fm/#/) which is a popular keyboard firmware for wired Keyboards. The reason i am using this firmware is that it works more reliable and doesn't have the problems i faced when i was trying to use [KMK](http://kmkfw.io).
### Keyboards RGB
This keyboard uses a microcontroller that has a on-board ws2812-2020
rgb led that is used for signaling on which layer you are, if caps lock is enabled, if num lock is enabled and if scroll lock is enabled.
### Upload Firmware
to compile and upload the firmware move to the working directory of your `qmk/qmkfirmware` and compile and upload the firmware using the `qmk flash -kb hardwired/marek128b/ergosplit40 -km vial` command. You can only compile the firmware using the `qmk compile -kb handwired/marek128b/ergosplit40 -km vial` command. With `-km` you can select the keymap you want to compile or flash with the keyboard. The `-kb` part selects the keyboard you want to work with.
