Arduino expansion board, suitable for esp8266

Overview

OLED display, can be connected to DHT12 (or DHT11) temperature and humidity sensor, APDS9930 gesture recognition module, SD card, with RGB light, and photoresistor. It is mainly used with another 8266 board I drew, and can also be used with other Arduino boards. Because the IO resources of 8266 are limited, some pins are reused and require the use of jumper caps. It is recommended that dht's female headers be used with round openings for a stable connection. The wiring is terrible. I did it before the exam. Because I was short on time, I used automatic wiring directly. There is still a certain gap between Lichuang's automatic wiring and AD.
