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. 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. 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 5V, OFF, and 3.3V. 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. 1. Breadboard-specific power module, compatible with 5V and 3.3V Suitable for MB102 breadboard 2. Input voltage: 6.5-12V (DC) or USB power supply 3. Output voltage: 3.3V, 5V, jumper cap selectable 4. Output current: Less than700ma (peak value) 5. The upper and lower channels are independently controlled and can be switched to 0V, 3.3V, and 5V.Two sets of onboard 3.3V and 5V DC output pins with self-locking switch indicator lights 1. The module inputs 6.5V-12V. If you input 5V, you will not get 5V voltage. There is a voltage difference between the input and output of the voltage stabilizing chip, otherwise it will not work. 2. If you only use 3.3V, the 5V output over there can get a stable voltage of 3.3V. 3. This is the power module without breadboard, thank you! DUE to Different Batches, The Apperance, Color and Printing of the Product May Be Different, which does not attract use. Color: As Shown Material: PCB Package Contents: 6*MB102 Breadboard Power Module
