ESP32-S3 dot RGB screen shrink development board

emm I bought all the screens, but it doesn’t make sense that it keeps gathering dust and not lighting up. .
So I made a reduction based on the schematic diagram of [Xiao Zhazha’s 86 Box](https://oshwhub.com/myzhazha/esp32s3_86-kai-fa-ban).

Compared with his version, the differences include:
* Appearance Changed to 50mm*50mm square; if its shape is not used, naturally its shell cannot be used
* His version only supports 3SPI+RGB666 screen, mine adds a 40P RGB888 screen interface with resistive touch, but the two screens cannot be used at the same time Lights up
* The INT of the touch screen is connected to the main control alone, and there is no need to choose between audio and audio
* The download circuit is shortened, you need to use a serial port module with EN and reset output for downloading
* The original DC-DC is too expensive, so it is shortened to Ordinary buck with 100% conduction
* Shrunk several pieces of MAX98357A and replaced it with several pieces of 8002, high-fidelity output up to 8bit/tens of kHz, tears of regret (?)
* 4056 charging shrink The indicator light is removed, but the ESP32 can read the battery voltage (roughly, with an error of tens of mV) and charging status (charging/full)
* The position of the resistive touch controller NS2009 is reserved for the 40P RGB888 resistive touch screen and verified Now it can be used
* The battery interface is changed to 1.25 3P with NTC, and it supports high temperature protection
* The long press switch IC is retained~~so you know that I copied his 86 box~~, but compared with his, this one The power on/off button can be recognized by the ESP32
* There is no change in the TF card part
* The position of the external low voltage reset IC is reserved to prevent the ESP32 from being confused when the voltage is low; however, due to shrinkage, it is not soldered or tested
* The pin header is drawn out The model of the FPC socket in the I2C and screen's 3-wire SPI

BOM is not accurate. I just dragged a package for use. It is recommended that you buy the kind of accessory with a back flip that can be inserted on both sides.
The verification code for each hardware function is provided
