The latest Raspberry Pi Zero W comes with wifi and bluetooth built-in at $10. Which is great because it makes it perfect for IoT projects. But if you had previously bought a bunch of Raspberry Pi Zero or want to keep the new Raspberry Pi Zero projects low cost, you probably will go with the option of adding WiFi easily and cleanly to your existing or new Raspberry Pi Zero boards; without adding much bulk to the compact board.
Pial’s Blog goes into detail on how to do just that without using the Zero’s OTG USB port.
