These are really nice, and they provide a stable power source at 3V3 and 5V. However, the switch does not appear to have any effect on the power supplied on the solder pads. As such, I'm not sure the undercurrent protection works when using those. I'm using protected 18650 batteries so I don't really care.

Works as expected, very happy to have found this item.

Excellent pour IoT

good for little projects.

Ok

Very good board. Outputs very clean 3,3V and 5V. Treats the LiIon batteries well. Switch only cuts power to the USB-A Socket. The output ports on each side of the board (3,3V and 5V) are always active.

received in good state, still to be tested, waiting for the batteries

muito bom o acabamento

good and cheap

works great!
