How to Use MB102 Breadboard Power Supply Module 3.3V/5V - Direct V output: Examples, Pinouts, and Specs

The MB102 Breadboard Power Supply Module by CorpCo is a compact and versatile power supply solution designed specifically for breadboard-based prototyping. It provides stable output voltages of 3.3V and 5V, making it ideal for powering a wide range of electronic components and microcontroller projects. The module connects directly to standard breadboards, simplifying the process of powering circuits without the need for external wiring or bulky power supplies.

• Powering microcontrollers such as Arduino, ESP32, and Raspberry Pi Pico.
• Supplying power to sensors, actuators, and other electronic components.
• Prototyping and testing circuits on breadboards.
• Educational and hobbyist electronics projects.

The following table outlines the key technical details of the MB102 Breadboard Power Supply Module:

The MB102 module has several key connectors and pins. The table below describes their functions:

1. Connect the Module to a Breadboard:

   • Align the module's pins with the power rails of a standard 830-point breadboard.
   • Gently press the module into the breadboard until it is securely seated.

2. Provide Input Power:

   • Use a DC adapter (6.5V - 12V) to supply power via the DC barrel jack.
   • Alternatively, connect a 5V USB power source to the USB Type-A port.

3. Set the Output Voltage:

   • Use the voltage selector jumpers to choose between 3.3V and 5V for each power rail.
   • Ensure the jumpers are securely placed in the desired position.

4. Power On the Module:

   • Slide the power switch to the ON position.
   • Verify that the LED indicator lights up, confirming the module is powered.

5. Connect Your Circuit:

   • Use the breadboard power rails (VCC and GND) to distribute power to your circuit components.

• Input Voltage Range: Ensure the input voltage does not exceed the specified range (6.5V - 12V DC) to avoid damaging the module.
• Current Limitations: The module can supply a maximum current of 700mA. Avoid overloading the module to prevent overheating or failure.
• Voltage Selection: Double-check the voltage selector jumpers before powering your circuit to ensure the correct voltage is supplied.
• Breadboard Compatibility: The module is designed for standard 830-point breadboards. It may not fit smaller or non-standard breadboards.

Below is an example of how to use the MB102 module to power an Arduino UNO via a breadboard:

1. Connect the MB102 module to the breadboard.
2. Set the voltage selector jumper to 5V.
3. Use jumper wires to connect the breadboard's VCC and GND rails to the Arduino UNO's 5V and GND pins, respectively.
4. Power the MB102 module using a 9V DC adapter.

// Example: Blink an LED using Arduino UNO powered by MB102 module

const int ledPin = 13; // Pin connected to the onboard LED

void setup() {
  pinMode(ledPin, OUTPUT); // Set the LED pin as an output
}

void loop() {
  digitalWrite(ledPin, HIGH); // Turn the LED on
  delay(1000);                // Wait for 1 second
  digitalWrite(ledPin, LOW);  // Turn the LED off
  delay(1000);                // Wait for 1 second
}

1. Can I use the MB102 module to power a Raspberry Pi?

   • No, the MB102 module cannot supply the high current required by a Raspberry Pi. Use a dedicated power supply for Raspberry Pi boards.

2. What happens if I reverse the input polarity?

   • The MB102 module does not have reverse polarity protection. Reversing the input polarity may permanently damage the module.

3. Can I use both the DC barrel jack and USB input simultaneously?

   • No, use only one input source at a time to avoid potential damage or instability.

4. Is the module compatible with smaller breadboards?

   • The MB102 is designed for standard 830-point breadboards. It may not fit smaller or non-standard breadboards.
