Simple esp8266 digital tube clock

Updated in 20211019, in response to the needs of friends, the schematic diagram and pcb diagram of the conventional esp8266 (esp12F) are added

I accidentally got a chip that was similar to the 8266, but the pin package was different, so I drew a separate board.

For board making, directly use the Gerber_PCBXXX in the attachment.

Because the PCB Lichuang import will automatically re-lay the copper, there will be problems, mainly in the 8266 antenna area. I made the slot first and then automatically routed and laid the copper and then removed the slot area. If the copper is re-layed, the antenna area will also be laid with copper. You need to modify it yourself and generate the Gerber file.

Digital tube uses 8-bit digital tube max7219 series, program folder "ESP8266_Network_Clock_7SEGMAX7219"

If you don't want to make a clock and use it as a development board, just solder two 8p pin headers.

The board of Zeyao Technology does not have circuits such as ch340, so you need to connect usb to ttl to download manually (after connecting usb to ttl, press and hold the rst and flash buttons at the same time, then release rst, and then release the flash button to enter the download model). (Verified to work normally)

The conventional esp8266 has a ch340 circuit added and can be downloaded directly from typec. (Not verified, I hope someone can reply in the comments section)

1. Unique 8266 package

2. Compared with 12f, the package size is obviously different.

3. Blank board

4. After welding

5. Prepare to solder the digital tube

6. Finished product display

7. Effect after turning on the power
