This is a Nano I've had for around a year, it's from Keyestudio, a bit expensive though.
Th first one I've seen with a crystal next to a CH340 USB controller.
The mod is similar to the previous posted Board 2.
I posted this somewhere else but I'll repeat it here.
I finally downloaded that file I was after and it only gives two BOR options, the lower voltage setting is marked as reserved.
The Nanos I have checked are set to Mid setting of between 2.5 - 2.7 range.
I will go through the other clones when I add the headers. The lowest setting is marked as reserved. (No 1.8v option shown)
I have to say that using the small Programmer with a modified Nano is actually nice because:
When writing code in the Arduino IDE and then uploading it to test, requires any other program using the Com port, like a Console Terminal program to be disconnected, after the upload has finished, it has to be reconnected again. It does not sound like much, but after a while it grinds on me.
Using the Programmer with AvrDudess allows you to point this program to the compiler output directory used by the IDE. So I build-verify the code in the IDE as normal, then Press Upload in the AVR program window and it's done.
Yes you can do this with the IDE, but there are options available to speed the upload up which are not available in the IDE - you can go behind the scenes and make edits, but what a PIA.
The big advantage is that the USB port on the Nano is not used to program, it remains connected the the Terminal Coms program, and debug or other output streams to the Terminal program when the upload is finished.
