ceiling1 aka YIXD05YI support

[fgsfds]

YIXD05YI does seem to have ESP, but I barely have any experience with it, so I require someone's assistance. Thanks in advance.

Could you provide some more photos of the mainboard? Do you have a continuity tester or multimeter to check the continuity between the pin header (4 pins) and the pads of the ESP32?

[fgsfds]

I have a multimeter

[syssi]

Please measure the continuity / resistance between the pins of the pin header and the ESP32. May you could label the corresponding pads here:

What am I looking for? I checked one of the header pins, and there is resistance between it and multiple esp pins (like 10, 14 and 25).

[syssi]

We are looking for continuity (resistance = 0 ohm). Is there a connection between the pin header pins and the ESP pads? This is what I'm looking for: Let's assume the pin header is connection to 3V3, GND, TXD and RXD (of the ESP) it could be used to flash the ESP easily.

I don't think any of these pins are TX/RX. That's what I got

Two bottom pins have zero resistance between ground and 3v3
