Is there a KiCad symbol and footprint for the S2-LPQ?
Yes. The symbol is EasyEDA_Cloud:S2-LPQTR and the footprint EasyEDA_Cloud:VQFN-24_L4.0-W4.0-P0.50-TL-EP2.7, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the S2-LPQ?
QFN-24-EP(4x4), with 25 pins. Its footprint is drawn on this page.
Where is the S2-LPQ datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the S2-LPQ?
JLCPCB lists it as part C880591, with 4,000 in stock; the sellers' links on this page open their listings.
What can replace the S2-LPQ?
Parts like it in the library: the CYRF8935A-24LQXC by Infineon Technologies, the MICRF405YML-TR by Microchip Technology, the NRF24LE1-F16Q24-T by Nordic Semicon and the S2-LPTXQ by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
