ESP32-Cam programming board revisited

For an index to all my stories click this text

I got some response from a reader who build my ESP32-Cam programming board and he had some trouble when working with it. You can find the board here: http://lucstechblog.blogspot.com/2021/09/esp32cam-programming-board.html

The problem was that connection to the ESP32-Cam was very slow and when connected the video framerate was veerryyyyyyy sloooooooowwwww.

After some tests I discovered that in certain circumstances wifi transfer was blocked or at least slowed down by having the ESP-32 Cam so close to the strip board. This might be caused by the copper side of the stripboard blocking the wifi transfer.

The solution however is simple.



I have several Wemos D1 mini's and they always came with a variety of headers. Some of these headers had long pins. And the ESP32-Cam has the same footprint.



Use these as an extension for the headers on the programming board and the ESP-32 Cam will be lifted to a greater distance from the stripboard and the problem is solved.

This might not be aesthetically pleasing but this board's only purpose is to make programming the ESP32-Cam easier.

Till next time
have fun
