Questions

Is there a KiCad symbol and footprint for the NSM-U1?

Yes. The symbol is EasyEDA_Cloud:NSM-U1 and the footprint EasyEDA_Cloud:COMM-SMD_44P-L17.7-W15.8-P1.10, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the NSM-U1?

SMD,17.7x15.8mm, with 44 pins. Its footprint is drawn on this page.

Where is the NSM-U1 datasheet?

techphant publishes it: the Datasheet link on this page opens it.

Where can I order the NSM-U1?

JLCPCB lists it as part C22400304, with 1,048 in stock; the sellers' links on this page open their listings.

What can replace the NSM-U1?

Parts like it in the library: the TP1107 by techphant, the TP2210 by techphant, the VG5549S490N1S1 by Vollgo and the E30-490T20D by Chengdu Ebyte Elec Tech. Check their datasheets: a part that fits the footprint may still differ in its ratings.
