MB-102 Breadboard ,Arduino Board Solderless Breadboard.multiple power supply The module provides dual 5 V and 3.3 V power rails, and has a multi-purpose female USB socket, convenient external lead use.

Fits perfectly on arduino board solderless breadboard and provides both 3.3v and 5v, Doesn't have a ton of power, For MB102 breadboard, two way independent control, can be switched to 0V, 3.3V, 5V.Short Circuit Protection.

Output voltage switchable .Fluctuation two road independent control, jumper pins are utilised for selecting the voltage levels on each side of the breadboard power rails. You can choose between 5 V, OFF, and 3.3 V.

Short circuit alarm,The green power LED is connected to the output rail, when you applied a short to either of the voltage rails it would go out, this is an excellent indicator of a short in the power.

Input Voltage : DC 6.5-12V; Output Voltage : DC 3.3V 5V; Input do not exceed 700mA,Locking ON / OFF Switch, no need to unplug the power adapter,LED Power Indicator indicated when the board is powered up.
