The Raspberry Pi Zero captivates with its small dimensions. This comes at a cost, however, with only one micro USB port available for peripherals of any kind. In this scenario you’ll probably think twice about what you connect to that port. “A USB hub” may sound like a natural choice but if you’re like me, you’ll want to carry the gadget around a bit and minimize the number of accessories.
Now there are solutions to stack a USB hub onto the Pi Zero, eg. Circuitbeard’s one or Richard Hawthorn’s one, but actually I don’t want to carry around a USB keyboard, especially if I have no HDMI-capable display around at all times. Instead I want to login onto the Pi via Wifi while still having Internet connectivity even when not at home. Thus I want the Pi to be an access point AND maintain a Wifi client connection at the same time. This is rather easy to do with two USB wifi adapters — but with the Pi Zero we’ll have to do with a single one!
