“The zero has wifi and bluetooth, but be wary of using them simultaneously. My bluetooth connections were unstable when using wifi and vice-versa. As bluetooth is essential for the project I'm working on I disabled WiFi. When I need a network connection to the board I connect it directly to my laptop via USB where it emulates a USB NIC, so I didn't even need to buy a usb ethernet adapter :D https://github.com/hughsaunders/rccarpi”
