I would say it matches it just isn’t to scale. It has a board with four pins and the antenna.
The ones in the breadboard view are called castellated holes or plated half-holes and the module may come that way or the OP has cut off the edge of their PCB to make the holes castellated like that. That would explain why the PCB is an SMD part. It is a great way to use those cheap modules on a pcb without having the pcb becoming a couple of CM thick with headers.
