I am confused as to why the gopigo kit which ships with the PI3 still ships with the wifi dongle. Past post seem to indicate that it is not needed but the product list still list it. Its a minor point but I have to ask.
It is included for CINCH. CINCH allows forneasier networking, by creating a WiFi hotspot and allowing remote connections quite easily. The WiFi dongle is necessary for creating a hotspot with CINH.
