【ART-Pi】Ink screen weather forecast clock

An ink screen weather forecast clock based on Art-Pi, with a 24p standard serial port spi ink screen fpc interface, and the shape is adapted to the WF0327 ink screen. This board has the following functions:

1. The most basic one has an ink screen interface.
2. Two buttons are reserved to facilitate adding functions later.
3. Using RX8025 as an external RTC chip is more accurate and also provides the possibility of low power consumption.
4. A cr1220 button battery is reserved to power the RX8025 and the RTC on the bottom board.
5. An NFC chip has been added to provide the possibility of using NFC to transmit data.
6. A lithium battery charging chip is added, and the 5v drawn from the base plate is used for charging.
7. A dcdc chip is used to step down the lithium battery to 3.3v and connect it directly to the base plate, so that it can continue to operate without being plugged in (the operating voltage of the components on the base plate is all 3.3v, so this operation is possible)
8. A passive buzzer has been added, which can be used as an alarm clock or play music (total loss of sound quality warning)
9. An AHT20 chip is used as a temperature and humidity sensor to obtain indoor temperature and humidity in real time.
10. Two LEDs are reserved to indicate more working statuses
11. A photoresistor is added to automatically stop working in dark places to save electricity.
