# Introduction

{% hint style="danger" %}
Be careful around the LEDs, the perimeter ones are fragile!
{% endhint %}

#### In order to reach ***MAXIMUM BRIGHTNESS*** **you will need to flash the pre-compiled file on the** [**github repo**](https://github.com/RGBKB/Keyboard-files/tree/master/Sol/Flashing%20files) **or compile your keymap with "**&#x52;GBLIGHT\_FULL\_POWER = yes" in rules.mk <a href="#in-order-to-reach-maximum-brightness-you-will-need-to-flash-the-pre-compiled-file-on-the-github-repo" id="in-order-to-reach-maximum-brightness-you-will-need-to-flash-the-pre-compiled-file-on-the-github-repo"></a>

* **(Optional)** [**Compatible OLED**](https://www.amazon.com/gp/product/B079BN2J8V/ref=oh_aui_detailpage_o06_s01?ie=UTF8\&psc=1) **panels must use the SSD1306 Driver**
* **(Optional)** [**Rotary Encoder**](https://mkultra.click/collections/switches/products/industrial-rotary-encoder)**, most marked for Arduino will work, none with the PCB included**

### **Detailed part notes:** <a href="#detailed-part-notes" id="detailed-part-notes"></a>

* MX switches which support SMD LEDs will give the best backlighting effect. Almost all Kailh switches have a cutout for the LED. All Kailh Choc low profile switches also have a cutout for the LED. Kailh BOX/Choc switches will not be able to have their tops opened after soldering. Cherry and Gateron have a lineup of RGB switches. Any switch with a transparent bottom housing will work great.
* The PCB supports Holtite 8P2/8P2 sockets for the MX holes.. The Mill-Max sockets that are popular may not work.
* For tenting you can get two pairs of the standard CNC feet that most 60% cases come with (found [here](https://kbdfans.cn/products/anodized-cnc-aluminum-feet-1pair) or [here](https://www.amazon.com/dp/B07H14TQDX/ref=cm_sw_r_cp_ep_dp_W.2UBbDARSXDD?th=1)) These will give you a \~5deg tilt.
