USB HUB + WiFi Teardown

One day I come across an interesting product from Adafruit that I couldn't resist getting. It will make a nice addition to the Raspberry Pi Zero. It's a 3 port USB hub with inbuilt WiFi which takes the fourth port. Inspired by insideGadgets, here are some photos and part numbers.

Wish it was a bit more compact. I have a USB to OTG adapter in the USB plug.

Interesting thing to note is the fourth USB port footprint, this PCB can support the WiFi module or fourth USB port. Overall it is a simple design that would be easy to embed in another project without the housing.
