Questions

Is there a KiCad symbol and footprint for the IIS2MDC?

Yes. The symbol is IIS2MDCTR:IIS2MDCTR and the footprint 4ms_Package_QFP:LGA-12_2x2mm_P0.5mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the IIS2MDC?

LGA-12(2x2), with 12 pins. Its footprint is drawn on this page.

Where is the IIS2MDC datasheet?

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

Where can I order the IIS2MDC?

JLCPCB lists it as part C2655002, with 3,326 in stock; the sellers' links on this page open their listings.

What can replace the IIS2MDC?

Parts like it in the library: the LIS3MDL by STMicroelectronics and the LIS2MDL by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the IIS2MDC?

8 boards in 7 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
