Questions

Is there a KiCad symbol and footprint for the R1M?

Yes. The symbol is Device:D and the footprint Diode_SMD:D_SOD-123F, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the R1M?

SOD-123FL, with 2 pins. Its footprint is drawn on this page.

Where can I order the R1M?

JLCPCB lists it as part C53222272, with 563 in stock; the sellers' links on this page open their listings.

What can replace the R1M?

Parts like it in the library: the F7 by GOODWORK, the FR107W by hongjiacheng, the SOD1F7 by MDD and the US1MW by hongjiacheng. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the R1M?

15 boards in 9 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
