Is there a KiCad symbol and footprint for the BL0939?
Yes. The symbol is EasyEDA_Cloud:BL0939_C2841044 and the footprint EasyEDA_Cloud:SSOP-20L_L8.7-W3.9-P0.64-LS6.0-BL, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BL0939?
SOP-16, with 20 pins. Its footprint is drawn on this page.
Where is the BL0939 datasheet?
BL publishes it: the Datasheet link on this page opens it.
Where can I order the BL0939?
JLCPCB lists it as part C2841044, with 6,786 in stock; the sellers' links on this page open their listings.
What can replace the BL0939?
Parts like it in the library: the SSP1839 by Shanghai Siproin Microelectronics, the BL0942 by BL, the BL0940 by BL and the BL0930F by BL. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the BL0939?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
