    this piece is very usefull for powerup arduino like boards, the double channel permitting to choose 2 different voltage on each channel 3.3 v and 5v , there are 2 switch to select the output. It fit perfectly on 8.5x5.5 cm Tie points solderless Breadboard.

    Overall nice design with good number of decoupling capacitors on the output and a 500mA resettable fuse on the USB input. Both rails are able to switch between 5V and 3.3V which is a plus. Has the correct pin pitch to fit on the supply rails of the breadboard The only negative of the breadboard supply is that it's made with a rather thin 1.2mm PCB. It still works fine but would've preferred something slightly thicker.

    it works perfectly just connect the mini usb to the module and use your breadbord as you want. it makes your experimenting with circuits much more easy it works with 5v and 3.3V

    Nice unit.. caution thar usb input routes power to 3.3v regulator by backfeeding through 5v regulator. Anything but a minimal 3.3v load will probably damage the 5v regulator.

    This is fine for light duty. Note that the power rails are reversed on one side (positive is on outside on one side , and on the inside on the other side of the bread board). Allows full access to bread board pins at the board is offset to hang over the side

    5V ouput is only a mirror of the 5V delivered by your USB charger if used. So if charger provides less than 5V, you will not get 5V in the 5V rail. Better use an external power supply giving at least 7V. Otherwise, good
