# Can't find component from schematics

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.

• Ok, thanks! Does it have a standard name? I can't find it in EasyEDA to draw it. – Miguel Mar 17 '20 at 10:44
• @Miguel - see Andy's answer below. And no problem! – awjlogan Mar 17 '20 at 10:54

"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.

In EasyEDA you are probably looking for something with a name like this:
