Specification: Input voltage: 6.5-9V (DC) or USB power supply Output voltage: 3.3V, 5V switchable Maximum output current;700mA Two-way independent control can be switched to 0V, 3.3V, 5V Onboard two 3.3V, 5V DC output pin Feature: ++ Easy to use power supply board for use with the MB102 Breadboards. ++ The MB102 bread board, with two way independent control, the board can be switch between 0V, 3.3V, 5V. On-board there are two sets of 3.3V, 5V DC output pins, you can have two different voltages or both can be set the same. ++ The voltage outputs are set by jumpers on each output. The board can be powered from a wall wort power supply 6.5-12volts. ++ Do not exceed 700ma current draw or you can damage the power supply board. Package Include: 3 x Power Supply Module 3 x Male DC Power Pigtail Cable See more

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. 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 5V, OFF, and 3.3V. Male DC power pigtail cable, easy to weld and install, 18AWG DC power cable provides a more safer DIY solution for DC power connectivity. 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. Breadboard power supply module, for Ar-duino board solderless breadboard. The module provides dual 5V and 3.3V power rails, and has a multi-purpose female USB socket, convenient external lead use.
