# Corne Max & R2G

The Corne Max/R2G PCB is plug and play, so to get moving with the very basics, you should simply be able to plug it in to your device and start typing on it right away. \


Check over your keyboard to make sure it is what you ordered and has no visible damage. If you have any issues, please [just reach out to us!](https://www.mechboards.co.uk/support)

## Changing Keymap

If you are using a Chrome or Edge based browser, use the [usevia.app](https://usevia.app/#/) website&#x20;to change your keymap layout. You can also try the [standalone app](https://github.com/the-via/releases/releases). Make sure to connect the correct HID device when prompted.

## Changing RGB Settings

If you want to change the RGB lighting settings, the way to do this with the basic keymap is to go to layer 4 (pressing the fn1 and fn2 key together) and using the keys in the image below.

## Changing RGB Through VIA

If you want to change RGB through VIA, you can reflash using this file

{% hint style="warning" %}
Awaiting file - check back soon
{% endhint %}

Reflashing:

1. Unplug the USB cable from the left half
2. Unplug the TRRS cable from either half
3. Replug the USB cable into one half
4. Double-click the reset button found on the underside of the PCB.
5. A window will pop up (or find a new device called "RPI-RP2"), download the respective file from the link above and copy that files into the main RPI-RP2 directory. The windows should automatically close.
6. Unplug the USB cable from the flashed side and plug into the other half
7. Repeat steps 4 & 5
8. Unplug the second side
9. Replug the TRRS cable into both halves BEFORE replugging the USB cable. Make sure the TRRS cable is fully inserted into both halves
10. Replug the USB cable to the left half

## Corne Max LCD Screens

You can also use the Corne Max Helper software to get more out of your Corne Max which can be found here - [https://github.com/e11i0t23/CorneMAXHelper/releases/](https://github.com/e11i0t23/CorneMAXHelper/releases/) - Once installed, you can right click the icon in task bar to see what more options you have available through the app.

{% hint style="warning" %}
You do NOT need the software to use the keyboard, but it does add functionality to the LCD screens
