Waveshare USB HUB HAT (B) for Raspberry Pi Series with 4x USB 2.0 Ports

Not every project needs the Ethernet expansion a combined hub HAT provides - sometimes the only thing missing is enough USB ports, and this simpler HAT addresses exactly that, adding four USB 2.0 ports to a Raspberry Pi in one add-on. It's the more affordable, focused option when a build is already using wireless networking or a different Ethernet solution and just needs room to plug in more USB peripherals - a keyboard, a flash drive, a sensor dongle - than the Pi's own limited port count allows.
