Outline and pin positions checked against the manufacturer datasheet (C54796804 YY-1615BRGJ26-07-FI A.0 p2). Portrait body 1.50 wide x 1.60 tall. Top view: 4 top-left, 1 top-right, 3 bottom-left, 2 bottom-right (clockwise from the top-right). The schematic gives 1 DIN, 2 GND, 3 DOUT, 4 VDD, the opposite assignment to the 0807 sheets. Bottom pads 0.6 x 0.4 mm, 0.8 mm between rows (PCB land 0.75 x 0.65 mm). What this means.
