NodeMCU v3 differences in components on the board: ESP8266, missing parts, their functions and impac

ESP8266 NodeMCU v3
I purchased the board and noticed the missing components compared to other boards.
What are these components for and does their absence make any difference?
In the pictures you can see the difference

From the catalogue note of the CH340 chip:

Quote:

For CH340C/E/B chip, crystal X2 and capacitor C6, C7 are not required

And

Quote:

For CH340G/T/R chip, Crystal X2, capacitor C6 and C7 are used for clock oscillation circuit

You can see that the C version is used, in the second picture the G version.

The first difference I noticed was the flash mode.
You have to press the flash button and connect to the usb, then you can only upload software.

Both boards have the transistors required for auto-flash mode, but this CH340 without the quartz works poorly. On another forum someone had a board with a MEGA2560 with such a module, but with a worn designation and no confirmation of what version of CH340 it actually is, he also indicated a lack of reset before uploading, only with the MEGA it's even more of a problem because you have to target the time window, the ESP happily stands in flashing mode and waits for the batch for the next reset, the board resets itself during uploading, overall not very happily.
As in your case the autoreset doesn't work, it's a lame copy of the Node MCU and as if I could return it within the "14 days" it would already be going to the vendor.
