Outline and pin positions checked against the manufacturer datasheet (C55382860 BQ-1615GRBH-M5 rev 01 p3). Top view circled numbers: 1 top-left, 2 top-right, 3 bottom-right, 4 bottom-left (clockwise); the schematic gives 1 DIN, 2 GND, 3 DOUT, 4 VDD. Pad sizes are estimates (the PCB land is 0.7 x 0.8 mm with a 0.25 mm row gap). What this means.
