The weather adopts the free version of Xinzhi Weather (the cities provided by Xinzhi Weather are limited, and most county-level cities cannot obtain weather. It is recommended to try more superior cities or surrounding cities).
The ink screen adopts Jiaxian three-color 4.2-inch ink screen 
PCB adopts the latest half-sugar version. 4.2pcb Thanks to the half-sugar version pcb open source link  https://oshwhub.com/HalfSweet/ThreeColorEPaper

The following content is extremely important! ! ! !

First, it is recommended to flash the duck version or other compatible version firmware to ensure that the hardware is OK, then make sure the screen is selected correctly, and finally test this firmware.

The testing time of this firmware is limited, and my level is even more limited, so it is certain that there are bugs. Many forms are not designed to be fool-proof, so please fill in according to the general rules and prompts. I most likely do not have the ability to fix various bugs!

This firmware provides firmware bin download for enthusiasts to experience and use. In order to prevent JS from being used for profit, the verification code mechanism is enabled in the firmware. Without the verification code, some functions and programs will be affected .

For personal use, please contact the site via private message and provide the chip ID of the network configuration page. Each person will be provided with one verification code for free. Those who require more than one verification code will be treated as JS, and redundant verification codes will not be provided.

There is no guarantee that everyone will reply to the verification code within a few days, and the online time is not fixed. I hope everyone understands.

I am not very good at it. If you have professional technical problems and various other problems, please solve them by yourself, including but not limited to pcb BOM table, welding, purchase link, unable to flash firmware, ink screen does not display, distribution network interface does not display, weather forecast Not displayed, blah blah blah blah...

Updated content 1.01 1. Bug fixes

                        2. The useless arduino OTA function has been removed. Maybe the space is enough for the http OTA function, but I have not tested it (although there were two OTAs before, there was not enough space to use either one -_-b)

                        3. Removed the debug output and commented out all the output with one click. New bugs may appear.
