The ESP32-WROOM and ESP-12F 8266 boards have been actually verified.
First of all, I would like to thank Jialichuang for the free PCB proofing. Although it is a free proofing, the board is really beautiful^-^. I have made it several times this year. Let’s take a look at the board:
First of all, thank you to the following projects for sharing

Changes:
1. The purpose of the modification here is mainly because I felt that the original project board was a bit too big or did not meet my needs, so I made some changes.
2. In addition, the use of spring pins has been changed a bit.
3. Removed some burning interface switches that were originally considered unnecessary.
4. The USB interface has been replaced by Micro-USB. This USB cable is widely used. If you need Type-C, you can change it yourself. Anyway, it is very simple.
Verification instructions:
1. I only have ESP32-WROOM on hand, so I only verified this. The two projects above ESP8266 have been verified. The theory should be no problem (in fact, the burning is mainly a matter of a few pins, not many complicated problems)
2. Of course, automatic burning is supported
The spring pin is the test pin used. It was introduced in the above two projects. The main thing is to bend the long pin a little, and then break it open a little. In the beginning, it was not broken, which caused it to get stuck or not make good contact. See the picture for details:
The left side is what it looks like after removing the magnetic beads. You can see that one is longer and the other is shorter. The right side is after processing. Pay attention to which leg is longer.
After processing, you can weld. If the length is not easy to control, you can adjust it slightly later.
Once the cleaning is completed, the finished product will be ready.
The one on the picture is ESP32-WROOM. I removed the shielding cover just out of curiosity^-^ ^-^ ^-^
