When power is supplied, there is no message in the monitor.
After a hardware reset, there is no message in the monitor.
No response to TX
Power supply: 3.3v/0.6a
Adapter: CP2102
I bought 25 chips, assembled 3 identical devices - all three are silent.
I can't figure out what I'm doing wrong.

I strongly suggest you go over the esp32 hardware design guidelines and see if your schematics match that. For instance, it says:

External Crystal Clock Source (Compulsory)

The ESP32 firmware only supports 40 MHz crystal.

and that is just one of a bunch of things I see you not doing in your schematic.

So, in the absence of an external crystal 40MHz, it is impossible to read the chip ID? The internal 8 MHz generator does not support the serial port?

So, thanks for the consultation, I am satisfied
