hanshuo-ESP32-4.2 ink screen

Overview

The weather clock is modified based on Hanshuo 4.2 ink label:
it is perfectly compatible with the original casing, and the roundness feels very good. The recommended thickness for PCB printing is 0.8mm-1mm;
it also uses a built-in 4.2 black and white two-color ink screen.
The following firmware is provided, directly burned, compatible with ESP32D and ESP32 solo.
Compatible with RTX clock chip and SHT30 temperature and humidity sensor.
There is a small bug in the firmware. When using wifi for the first time, you need to confirm whether it is connected. Sometimes it cannot be connected the first time and you need to connect it a second time.

The default black and white screen cable screen printing is HINK E042A13.
