component
JSM4057
Public Made by Adomby adom
JSMSEMI Battery Management, SOT-23-6L. Pinout extracted from the datasheet, KiCad symbol/footprint/3D.

orderable attributes: rebuild .lbr with adom-lbr 2.18.0 so MPN, MANUFACTURER and the distributor part numbers reach <technology> (LCSC_PN C963399). The published library carried no attributes at all, so a BOM had nothing to buy from. Distributor PNs matched on exact MPN AND corroborating manufacturer.
