“It fits my Pi Zero W perfectly. The use of USB stem completely eliminates the need of additional cables, I say it is a must for any Pi Zero. Also, you can use it with a powerbank to make it extra portable - controlled by SSH/VNC over your phone. And the USB stem allows you to use Pi Zero W as an Ethernet/Mass storage device. Totally recommend.”
“I bought one of these to solder to a PiZero W that I could just chuck in my laptop bag. I'm always tinkering with the Pi and this makes it so easy, no more cables - it plugs in just like a dongle.
You do need a good fine point to solder it, but anyone with average soldering skills should have no difficulty in doing so.”
