mb 102 breadboard power supply : collegeroadelectronics

The MB102 Breadboard Power Supply Module is a compact and reliable module designed to power electronic projects on a standard MB102 breadboard. It provides regulated 3.3V and 5V DC outputs that can be used to power microcontrollers, sensors, and other circuit components.

• Dual Output Voltages:
  Selectable 3.3V or 5V via jumpers for each side of the breadboard.

• Input Options:

  • DC Barrel Jack (6.5V–12V input)

  • USB Type-A connector (5V input)

• Output Current:
  Up to 700 mA (depending on input and regulator used).

• Independent Channels:
  Left and right power rails on the breadboard can be set independently to 3.3V or 5V.

• ON/OFF Switch:
  Built-in switch to control power delivery easily.

• Power Indicator LED:
  Green LED indicates module is powered and functioning.

• Overcurrent Protection:
  Integrated voltage regulator protects against overload and short-circuit.

• Pin Configuration:

  • Vin (Barrel Jack / USB Input) – Power input (DC 6.5–12V or 5V via USB)

  • Vout (3.3V / 5V) – Regulated output voltage selectable by jumper

  • GND – Common ground connection

  • Header Pins: Provide easy connection for breadboard and jumper wires.

    Applications:

    • Arduino and Raspberry Pi prototyping

    • Embedded system projects

    • Sensor testing and interfacing

    • Educational electronics experiments

    • Low-power robotics and IoT modules
