Questions
Is there a KiCad symbol and footprint for the BU04?
Yes. The symbol is EasyEDA_Cloud:BU04 and the footprint EasyEDA_Cloud:WIRELM-SMD_BU04, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BU04?
SMD,35.5x33.5mm, with 36 pins. Its footprint is drawn on this page.
Where is the BU04 datasheet?
Ai-Thinker publishes it: the Datasheet link on this page opens it.
Where can I order the BU04?
JLCPCB lists it as part C42420050, with 29 in stock; the sellers' links on this page open their listings.
What can replace the BU04?
Parts like it in the library: the MK8000PATR7.9-GC by Silicontra. Check their datasheets: a part that fits the footprint may still differ in its ratings.
