power supply module Description:
Name: Breadboard Power Supply Module
Input voltage: 6.5-12 V (DC) or USB power supply
Output voltage: 3.3V/5V can switch over
Maximum output current: Locking ON / OFF Switch
LED Power Indicator
Fluctuation two road independent control, can switch over to 0 V, 3.3 V, 5 V.
On-board Two sets of 3.3V, 5V DC output pins, Facilitate the external leads.

Two ports of power output. You can switch the power voltage of both ports between 3.3V and 5V by the jumper cap.

There is a green LED to indicate the presence of power, and an ON / OFF latching switch to control the power to the board.

3.3V/5V Power Supply Module provides dual 5 V and 3.3 V power rails, and has a multi-purpose female USB socket, can plugs directly into a solderless breadboard.

The power board that is very easy to use,it is for MB102 breadboard. You have two independent power supply 3.3V or 5V. You can have two different voltages, or you can set the two to the same. The voltage output is set by the jump line on each output.

Note:
1. The module inputs 6.5V-12V. If you input 5V, you will not get 5V voltage. There is a voltage difference at the input 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.
3.12V is a voltage limit. If the AD-DC adapter is used, it is recommended to use 9V to avoid the voltage unstable burning board. 4.Make sure that the module is correct on the bread board, so that the power supply is aligned with the red stripes.
