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

The MB102 Breadboard Power Supply Module by CorpCo (Part ID: Uno) 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 projects. This module is easy to use, fits snugly onto standard breadboards, and eliminates the need for bulky external power supplies.

• Powering microcontrollers (e.g., Arduino, ESP32, Raspberry Pi Pico)
• Supplying power to sensors, LEDs, and other low-power 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 pins and connectors. 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 place to ensure a secure connection.

2. Provide Input Power:

   • Use a DC power adapter (6.5V to 12V) and connect it to the DC barrel jack.
   • Alternatively, connect a USB power source (5V) 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 the power indicator LED lights up, confirming the module is operational.

5. Connect Components:

   • Use the breadboard's power and ground rails to supply power to your circuit components.

• Input Voltage Range: Ensure the input voltage is within the specified range (6.5V to 12V). Exceeding this range may damage 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 connecting sensitive components to avoid accidental damage.
• Heat Dissipation: If the module becomes warm during operation, ensure adequate ventilation to prevent overheating.

Below is an example of how to power an Arduino UNO using the MB102 module:

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 5V and GND rails to the Arduino UNO's 5V and GND pins, respectively.

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

// Define the LED pin
const int ledPin = 13;

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 with a 9V battery?

   • Yes, you can connect a 9V battery to the DC barrel jack, but ensure the battery can supply sufficient current for your circuit.

2. Is the module compatible with all breadboards?

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

3. What happens if I exceed the maximum current rating?

   • Exceeding 700mA may cause the module to overheat or shut down. Always calculate your circuit's current requirements beforehand.

4. Can I use both 3.3V and 5V outputs simultaneously?

   • Yes, you can configure one power rail for 3.3V and the other for 5V using the voltage selector jumpers.

By following this documentation, you can effectively use the MB102 Breadboard Power Supply Module for your electronic projects.
