Review on Enhance Your Raspberry Pi Zero Experience with MakerSpot's 4-Port Stackable USB Hub HAT (Camera Connector, Bluetooth & WiFi Supported) by Kevin Baker

I had to add USB ports to PI Zero. I came across this board which sounded attractive but the description of its installation was unclear. When it arrived I was confused by the 4 pogos until I realized they were pads on the PI Zero. Circuit board along with correct pad/pogo mounting orientation and alt! Four USB ports with virtually no extra effort! Works as described, right out of the box with no extra fuss! I'm excited! You might not want to use pogo pins for long term use, but for rapid prototyping this is great!
