Small ESP8266 development board

Project Description

The ESP8266 development boards on the market are generally larger in size, so I drew a smaller one, which is about 1/2 the original size.

Project function introduction

A simple ESP8266 development board with CH340C automatic download circuit is smaller and can be stuffed into a smaller box~

Circuit explanation

High school students cannot explain circuits. . . According to Espressif's official information, it has been verified that it can be used after soldering, and there are no problems with wiring. . . In short, you can't expect a high school student to do wiring professionally. . . Fortunately, the circuit can use certain components and you can change the resistance, capacity, etc. by yourself.

Because the shielding cover is relatively thick, I removed it. This is still the original PCB. The jumper has been added in the PCB file. Just use GerBer proofing. I will upload a few more pictures to reiterate: I am just a high school student     . His strength is still somewhat self-aware. . .

If there are any omissions or defects in the schematic or PCB, please let me know.Spray lightly

If there are any omissions or defects in the schematic or PCB, please help me point them out and I will see them. Thanks in advance!
