Re: Signal disturbance of ESP32-S3 module with pcb wifi antenna underneath a metal plate
That will likely negatively affect antenna performance, yes. Sorry, I don't know too much about RF magic to give an indication of how much. Another thing you may want to watch out for that I've had issues with in the past: if you manage to detune your antenna by a lot, you can get issues on WiFi ini...

Re: PSRAM integrated in the chip’s package
Yes, the psram is inside the package. No, you cannot add another psram chip externally and expect the amount of accessible memory available to increase, the chip does not support that.

Re: Wake up for a specific time after deep sleep
And yes, there is. You need to find some way to call deepSleepFunction 20 seconds after power up. You can either do that manually, by making sure the code path before the call to that function lasts 20 seconds (inserting delays strategically would indeed help there) or you could schedule a timer cal...

Re: Wake up for a specific time after deep sleep
Ah, never mind, I initially read over your deepSleepFunction code. What do you mean with 'it doesn't even execute the code and stays in a stagnant "on" state.'?

Re: Is the 8266 processor supported ?
Yes I found these (and some others). Interesting option, but not very much I/O pins (may or may not suffice for a particular task, although I also use I2C and SPI I/O extenders quite often). Also I don't think any of them have SPI RAM, do they? I'd like to have SPI RAM for receiving and buffering i...

Re: ESP32-C3 supermini serial port problem
That is very odd. Just to check it's not a hardware issue: can you reproduce it on other supermini boards as well?

Re: ESP32-S3FH4R2 - Unable to flash
Your image is unreadable potato quality; suggest you share it as a PDF rather than an image. Aside from that, please check the basics: are your voltage rails okay? Do you see 40MHz on the main crystal? Do you get any output on the serial port on power-on or reset?

Re: ESP32-C3FN4 Schematic review
USB-C specs say you should connect the receptacle to ground ( here , page 135) so you can get rid of C1/R3. I'd personally add an 10uF on VCC as well, but that's more intuition than grounded in theory. Wrt adding resistors/inductors, please follow the hardware reference guide , for instance the C3 d...
