The small mobile phone project based on Lishuang Taishan School

3.1-inch screen expansion board based on LCSC Taishanpai development board

Project Introduction
Project Tutorial Documents: VII. Mobile Phone Comprehensive Project - Feishu Cloud Documents (feishu.cn)
Based on the LCSC Taishanpai development board, this 3.1-inch screen expansion board can be directly connected to the Taishanpai development board. It also integrates a speaker interface and microphone, connecting to the Taishanpai via POGO spring pins. The Taishanpai MIPI interface connects to the Taishanpai DSI interface via a 31p 0.3mm co-directional FPC cable. The touch interface connects to the Taishanpai TP interface via a 6P FPC cable.
Partial BOM link:
4mm POGO pin.

This is a schematic design for a SY7021 backlight driver circuit from Taobao.com (0.3mm)
. R7 and R8 are pull-up and pull-down resistors, respectively. When R7 is soldered, the BL pin is pulled up to keep the backlight on before the backlight driver loads; conversely, when R7 is soldered, the BL pin is pulled up to keep the backlight off before the backlight driver loads. R5 and R6 are sampling resistors. One of them is not soldered
with a GP7101 backlight adjustment circuit; it is connected to the I2C1 interface of the Taishanpai circuit board. The backlight is adjusted via the I2C interface to control the output PWM . The backlight selection circuit
uses different 0-ohm resistors to select between the backlight from the Taishanpai MIPI interface and the onboard backlight driver circuit. The physical PCB soldering is complete, and the Taishanpai connection diagram is shown.
