FAQ

1 What is the MB-102 power module
It is a DC regulated power supply board designed specifically for breadboards offering stable dual output voltages of 5V and 3.3V for electronic circuit prototyping.

2 What input power options does this module support
It features both a USB Type-A port and a DC barrel jack allowing it to be powered either via a USB cable or an external power adapter.

3 How to choose between 5V and 3.3V output
The module uses yellow jumper caps. By adjusting the position of the jumper caps on the header pins you can flexibly toggle and select either 5V or 3.3V output.

4 What is the maximum output current per channel
Typically each output channel can provide approximately 700mA to 1A. The exact maximum current depends on the input voltage level and the heat dissipation conditions of the board.

5 What is the function of the onboard indicator light
It features an LED power indicator that lights up when the power is connected allowing users to visually confirm that the module is powered on and working properly.

6 Can it supply power to both the left and right power rails
Yes it supports dual output terminals. It can simultaneously supply power to both the positive and negative power rails on the left and right sides of a standard breadboard.

7 What input voltage should be used for the DC jack
When using the DC jack it is recommended that the input voltage from the adapter be between 6V and 12V. When using the USB interface the input is standard 5V.

8 What are the main application scenarios for this module
It is mainly used with solderless breadboards for rapid electronic circuit prototyping Arduino and microcontroller experiments and other testing projects requiring 5V or 3.3V.

9 Does the module have short circuit or overcurrent protection
Most of these modules incorporate thermal and current limiting protection within the voltage regulator chip itself providing basic safety protection in the event of an accidental short circuit on the output.

10 Is the module easy to install and use
It is very easy to use. It features a solderless design and can be quickly put into use simply by connecting its output terminals to the breadboard power rails using matching flat cables or jumper wires.
