Very newbie in the field of electronics and starting to learning about it and playing with EasyEDA. I'm copying a schematic and can't find the component I show in the named NM. What is it?
That's a 2 pin header. It's used so you can program the EEPROM - pulling
WP low on 24Cxx EEPROMs allows write access. It looks something like this:
The spacing between the pins is 2.54 mm (0.1"), and you connect the two pins together when you want to write to the EEPROM.
"NM" is likely to be an abbreviation for "not mounted" i.e. the symbol represents two solder pads in the circuit board that don't have a component fitted. The pin called "WP" on the CAT24C32 stands for "write protect" and without a solder link or header and bridge fitted (that pulls WP down to 0 volts) the chip cannot be written to. It's a form of protection as the name implies: -
Of course you can solder a two pin header to the PCB solder pads - it's optional but, on the schematic shown in the question, it's likely that there isn't a header fitted.
Does it have a standard name? I can't find it in EasyEDA to draw it
In EasyEDA you are probably looking for something with a name like this:
