Hi, I confirm that some S2 Mini clone boards have a routing problem on the C14 ground pad. After several hours of investigation (and one jeopardized board) the fix is straightforward. Scratch the ground plane a put a blob between the C14 cap and the ground plane. See attachment. The WiFi is now roc...

I have the same problem, 1 of 3 is working correctly and 2 works but when I use the wifi then they will sometimes reboot or just stop. I remove the EN pin and shortened the track ( so that it will not pick up noise from the RF antenna ),Did not help, I even connected the EN to 3v3 also did not help...

So the EN line is routed all the way down to the reset switch and it seems like somewhere along that trace it is picking up noise. Adding a small 22uF 6.3V cap along the edge of the reset switch is an easier place to tack on a cap as one side is ground and the other is the EN line. There is already ...

Verified the EN line is very noisy on bad esp32s2 mini boards and just holding the corner of the board by the EN pin smooths out the EN signal. I added a larger cap to between EN and ground and it seems to have cleaned the signal up and no more reboots. 5/7 of my esp32s2 minis has this same problem ...
