## 1.1 RGB Module Description

### 1.1.1 RGB Module Introduction

Hiwonder RGB Module's control system can deliver dynamic lighting effects such as flowing light, flashing, and rainbow patterns. It also features LEGO-compatible mounting holes, which are available for multi-DIY designs.

### 1.1.2 Working Principle

It uses two adjustable full-color RGB LEDs, each supporting independent control. You can set the brightness of each RGB LED individually, enabling multicolor mixing effects.

## 1.2 Notice

1.  Do not exceed the rated voltage range during use.

2.  Do not keep the RGB LEDs at their maximum brightness for too long to prevent overheating damage. Power off after extended use to cool down the device.
