That there is a plain Nano clone, not an Every. Every is a specific product, with unique features and a different processor.
No problem. Your English is better than my Russian! ![]()
When uploading to one of these boards with the unmarked UART chip (assuming that this is one of those), make sure to close the Serial Monitor first before clicking the 'Upload' icon. This is not normally needed, but these unidentified chips are known to misbehave.
(I recently had one of these fail suddenly in a similar fashion as shown in the linked thread in @sterretje's post - it still comes up as an FTDI device but the serial port fails to open. This results in the same error messages after 10 attempts - however I am not using Windows so the described driver rollback method does not apply. I have yet to test switching back to an older version of the Linux kernel. The MCU works and the board is still programmable via the ICSP header, so the board is still useable, just can't be programmed via serial. The reliability of these unmarked UART chips appears to be rather questionable.)
The rollback does not apply to FTDI, only CH340.
If you have a 16 pin usb-to-serial converter that identifies itself as an FTDI it a total fake (they are around).
Instead of rolling back the kernel, I simply booted into a Linux Mint partition on the PC that has not been updated or used for several months, but the older kernel (and hence driver) made no difference. I noted that the thread discussed CH340G but was curious to try it on this chip. Its obviously a weird hardware fault of some kind on this board and yes, although the chip reports as an FTDI, it is undoubtedly a fake. I purchased a handful of Nanos a while back and ended up with two with a UART that does not have markings and identify as FTDI. The remainder had marked CH340G chips. When it comes to these classic Nanos, Its a bit of a lottery what you end up with nowadays if you buy from Far East sites.
