LEB_4.3RGB_V1.1

Overview

Project Introduction:
1. This screen expansion board is compatible with the 01_RTC_LCD_v1.0 motherboard; if you want to adapt to other motherboards, you can refer to this design concept.
2. It is compatible with two 4.3-inch RGB capacitive touchscreens (resolution: 800*480), namely Puyang and Huadi Chuangxian; relevant information is provided below. If you need other information, you can contact the manufacturers. These two screens are a bit expensive; another relatively cheaper screen will be open-sourced later. It has been tested and is undergoing further verification.
3. You can further improve the screen driver circuit according to the manual. The circuit here has only been verified and may not be the most suitable for any particular screen. In addition, you can configure the current-configuring resistor according to the current required by the screen backlight.
