“This tool expands perfectly the one and only USB port of my Pi Zero. Unfortunately, if you power it up after the Pi zero, it will cause the Pi to restart, probably due to a current peak. Now that I know, it’s not really a problem anyway that’s why i’ll give 4 stars”
“Perfect add-on for the Pi-Zero also has a 3.5mm power socket which can back-power the Zero. With four full-sized USB sockets you can use wired or wireless keyboard/mouse, Wi-Fi dongle and still have a spare socket. Neat gizmo, highly recommended ... get one today :-)”
