What sets it apart is the board edge, straddle mount — the connector straddles the PCB edge and solders to pads on both sides, not a standard right-angle through-hole or SMT footprint. That makes it a fit for thin-profile designs where the USB port sits flush with the board edge, like a compact dongle or a card-edge I/O panel. The shell is shielded in steel and stainless steel, and the contacts are gold-plated.
Board layout — the straddle mount footprint
The board edge straddle mount means the connector's solder tails land on both the top and bottom PCB layers. The board must have a cutout at the edge for the connector body to sit into.
