Updated in 20211114. Since multiple PCBs are prone to problems, a separate project has been created. The source code can be used in the new project and the software is compatible.

At the same time, in order to be welding-friendly, the new hardware uses 12F.
Use the smallest chip 8266ex to light up the 1.4-inch 126*128 7735 display, with onboard antenna and memory chip, including an automatic download circuit.
This board is mainly drawn to verify whether the circuit of 8266ex is correct to facilitate the subsequent development of other objects. The display screen only has a demo version program, and those who need a weather clock must develop and modify it by themselves.
The high-definition video can be found on the Bilibili website. Likes and favorites are welcome, https://www.bilibili.com/video/BV1Hb4y1t7RQ/
1. Blank board
2. The appearance after welding
3. Screen style
4. Demo version demonstration
5. Install the acrylic shell effect
6. Family photos, there are too many 8266ex anyway, so I just posted them all.
