WIFI remote control receiver module

This design draws inspiration from two open-source projects: "Xiaomozi's" "Potato Remote Control 4G Remote Control Car" (https://oshwhub.com/xiaomozi/tu-dou-fa-she-ji-3-0) and "LE12138's" "Le Remote Control 2.0 | RC Remote Control Converted to 4G Remote Control" (https://oshwhub.com/LE12138/1f51ac624d2742d7a845f79a25eda0b2)  
, with slight hardware modifications.
The matching WIFI remote control transmitter module (8266 acquisition PPM) is linked here: https://oshwhub.com/myself1820/wifi-yuan-cheng-yao-kong-fa-she-mo-kuai-8266-cai-ji-ppm
Main functions of the circuit
: (1) Integrated DC-DC voltage regulator circuit, which can be connected to an external 2-4S lithium battery;
(2) Two USB outputs of 5V power supply, used to power the wireless network card and wireless WIFI camera;
(3) All IO ports are brought out, among which IO13/CH1, IO12/CH2, and IO14/CH3 have added level conversion circuits, which can drive the ESC or directly drive the WS2812 light strip;
(4) Reserved serial port interface, which can be used for downloading and debugging, or connected to an external GPS module.
(5) Reserved I2C interface, which can be used as a normal IO port or connected to an external screen.
(6) Two buttons on the board, one is a reset button and the other is used for network configuration (or other functions).
(7) One 5V output terminal (controlled by IO15), which can be connected to an external 5V lamp group.
(8) One ADC to collect input power voltage.

Other instructions
The program is referenced from the potato remote control 4G remote control car code of the master "xiaomozi" mentioned above. You need to modify the IO port configuration in the program. I will not put it here. You can modify it yourself according to the schematic diagram.
