Help Serial connection? Wiring?

[stevedee78]

What do I have to do to establish a serial connection to the camera?!

Seems like your model might be different, there should be 4 headers. In the one I have, they look like this: https://blog.express-it.nl/wp-content/uploads/2019/01/20190131_130729-2-2.jpg

Your model have connections on the back side of ESP, same as mine do.
Here is some good reference: fritz-smh/yi-hack#118 (comment)
You will need to solder wires to contacts and use serial-to-usb adapter.
I have same board, i only used 3 wires (gnd, tx, rx) and power was supplied via usb port.
Hope this helps.
