Questions

Is there a KiCad symbol and footprint for the BL0940?

Yes. The symbol is EasyEDA_Cloud:BL0940 and the footprint Package_SO:TSSOP-14_4.4x5mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the BL0940?

TSSOP-14, with 14 pins. Its footprint is drawn on this page.

Where is the BL0940 datasheet?

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

Where can I order the BL0940?

JLCPCB lists it as part C691894, with 0 in stock; the sellers' links on this page open their listings.

What can replace the BL0940?

Parts like it in the library: the SSP1840 by Shanghai Siproin Microelectronics, the BL0942 by BL, the BL0930F by BL and the SSP1842 by Shanghai Siproin Microelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the BL0940?

1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
