Overview

The Breadboard Power Supply Module provides a reliable, breadboard-ready power source for electronics prototyping. With selectable 3.3V and 5V outputs and multiple input options (USB or barrel jack), this compact module is ideal for powering microcontrollers, sensors, LEDs, and other low-power circuits.

Key Features

  • Dual voltage outputs: selectable 3.3V and 5V to support a wide range of components
  • Compatible with standard breadboards (fits MB102-style rails)
  • Power via USB (5V) or external DC barrel jack (6.5V to 12V)
  • Onboard voltage regulators for stable, consistent output
  • Simple jumper switch to toggle between voltages quickly
  • Two output channels allow simultaneous 3.3V and 5V use
  • Compact and lightweight for easy integration in prototypes

Specifications

  • Input Voltage: 6.5V to 12V (DC) via barrel jack, or 5V via USB
  • Output Voltage: 3.3V and 5V selectable via jumper
  • Max Output Current: 700mA
  • Dimensions: 5.3 cm x 3.5 cm x 2.5 cm
  • Output Channels: 2 (one for 3.3V, one for 5V)

Applications

  • Prototyping and testing circuits on breadboards
  • Microcontroller projects (Arduino, ESP8266/ESP32, etc.)
  • Sensor arrays and breakout modules
  • LED and display experiments

How to Use

  1. Insert the module pins into the breadboard power rails (align with MB102-style rails).
  2. Select the desired voltage using the jumper (3.3V or 5V).
  3. Connect a power source: plug in a USB cable (5V) or connect a DC adapter to the barrel jack (6.5V to 12V).
  4. Power your circuit and monitor load to ensure you remain within the 700mA limit.

Compatibility and Tips

  • This module is ideal for common prototyping boards and MB102-compatible breadboards.
  • When powering devices that draw close to 700mA, ensure adequate cooling and a stable power source.
  • Do not exceed the input voltage range to avoid damaging the onboard regulators.
