Schematic for said PCB.

FYI, the camera board is on the "official store":

The documentation for the official Espressif ESP32-S3-LCD-EV-Board makes several mentions of a USB Host plug on board, but I cannot seem to figure out how to get one. Any ideas?

See:

SOLVED: I was able to get this to work today. To use pad JTAG (such as my ESP-PROG), I needed to set the efuse STRAP_JTAG_SEL to one so that *GPIO3* can be used as a strapping pin to point the JTAG at the "pads" instead of USB-JTAG. I used a jumper to ground GPIO3.

There may be other solutions that ...

Thanks for your help! I posted an issue:

So everyone gave up? I'm interested in using the ESP-PROG 10-pin header with my S3 DevKitC and this page has some great info:

About the STRAP_JTAG_SEL strapping pin for being able to control whether standard (pad) JTAG or USB-JTAG is ...

It is 44 pins by my counting. I'd like to find one with the 10-pin JTAG brought out as well. Kind of like the JTAG adapter bare PCBs for the original ESP32.

Yeah this is the problem with not doing bare-metal coding. There is a LOT of other code running on the micro(s). RTOS, etc.

I'm pretty sure GPIO2 is usable, it's just a matter of finding out what code is squatting on it. That's where I didn't have time to investigate. Someone mentioned "unconfig ...

Are you sinking current from the supply through the LED to the GPIO? I don't know if there's enough current available to source it through the LED to ground (each case of course with a current limiting resistor).

I need to spend more time looking at the GPIO modes and pullup configuration before I ...

What OS version of WIndows supports this? I tried the Espressif demo and it worked on my phone but none of my PCs.
