ESP32CAM burning socket

After buying an ESP32CAM for free, I found that downloading and powering it were very troublesome. I needed to use Dupont cables and a burner. Then I thought about looking for a dedicated download socket online. It turned out that there was one available but not for sale, so I made one myself.

Automatic burning is invalid for ESP32CAM, because the ESP32 needs to be reset when IO0 is pulled down, and this ESP32CAM happens to not trigger a reset, so when downloading, you need to manually hold down the IO0 pull-down button to download.

It can also be used as a serial port debugging socket.

You can choose whether to lead out the 10 IO ports (ten patch pin header pads on the development board)

When developing using arduino IDE or VSC, you need to install the ESP32 library.

1.0PCB: The initial version, there is a problem with the circuit, and automatic downloading cannot be achieved.

2.0PCBP: The devices used for automatic downloading such as S8050 have been removed and replaced with purely manual pull-down IO0 downloading. CH340C has been replaced with CH340N.

The following is a physical picture of the initial version 1.0 (CH340C).
