This is an inexpensive addition to my Pi0s giving me 3 USB and ethernet ports. It connects via another USB mic and gives you all 40 pins for whatever you need. I have relatively few CPU projects so this hat makes the Pi0 perfect. The USB to USB adapter is a little flimsy in my opinion as it requires a little more fuss than most USBs and sticks out a little further than an RJ45 connector, but I'll print out a case for it once I'm done. .
