MB102 Breadboard Power Supply module is one of the essential and low-cost components in the electronics labs. It powers the circuits and is also used for testing purposes. The small compact module is power efficient and can be operated using an input voltage range of 6.5 Volts to 12 Volts. The module has two voltage regulators which output 3.3 Volts and 5 Volts. Mb-102 also has an onboard capacitor for noise suppression and smoothing the input voltage.
The module is facilitated with a switch to manually turn on/off the module while connected to the power source. It comes with an additional USB connector and berg headers which can also be configured accordingly. The component is useful especially for prototypes and small breadboard circuits.
The post is a quick guide to the pinout, features and specifications, interfacing applications.
Breadboard Power Supply module
The breadboard power supply module consists of:
Power Port & USB Port: The DC power port and USB-A connector are provided to the module to power it up.
Power Switch & LED: A switch is embedded to provide extra control along with an LED to indicate the energizing of the module.
Jumpers: The mb102 breadboard supply module is capable of giving out 3.3 volts or 5 volts to breadboard rails. They can be operated individually.
Berg Headers: The berg headers can be used to output power to other devices as well.

The schematic is provided for the visual and describes the circuitry of the breadboard based power supply module. This schematic diagram becomes handy when any of the components got damaged and we want to replace that component.
How to use BM102 Power Supply Module?
This helpful BBPS module comes in handy in a vast number of projects. It can be interfaced very easily.
To power the Breadboard
To power the breadboard through the BBPS module, mount it on to the breadboard. It should be placed in such a way that the left and right jumpers of the module coincide with the power rails of the breadboard. Connect the input power supply either regulated or unregulated to the DC input jack. Turn on the switch to check the LED. If the module is energized, the LED lights up. Adjust the jumper to the desired output voltage. If you want the bread power rails of 5 volts, adjust the jumper accordingly. The left and right jumpers are two independent channels and can provide different voltages simultaneously.
To power peripherals
Connect similarly as previously explained. Now use female jumpers to connect the berg headers to power up other components and microcontroller units. It is also selectable between 3.3Volts and 5 Volts.
