How to Use Elegoo Power Supply Module A Comprehensive Guide

If you’re working on electronics projects, having a reliable power supply module is essential. The Elegoo Power Supply Module is a popular choice among hobbyists and professionals alike due to its versatility, ease of use, and affordability. Whether you’re powering an Arduino board, breadboard circuits, or other electronic components, understanding how to properly use the Elegoo Power Supply Module can save you time and prevent damage to your components. In this article, we’ll walk you through everything you need to know about using the Elegoo Power Supply Module effectively.

Overview of the Elegoo Power Supply Module

The Elegoo Power Supply Module is designed to provide a stable 3.3V or 5V output to your breadboard or project. It typically plugs directly onto a standard breadboard, drawing power from an external DC source (usually 6.5V to 12V) or USB input. Its compact design includes voltage selection switches, power indicators, and short circuit protection, making it an ideal power solution for prototyping and educational purposes.

Understanding the Power Input Options

The Elegoo Power Supply Module can be powered through two main methods:

DC Barrel Jack Input: This input accepts a DC voltage between 6.5V and 12V. You can use a wall adapter or a battery pack with a matching voltage range. This method offers stable power for longer projects.

USB Input: The module also features a USB port that allows you to power it using a standard 5V USB connection. This is convenient for powering the module from a computer or USB power bank.

Make sure to use only one power input at a time to avoid damaging the module.

Installing the Module on a Breadboard

To use the Elegoo Power Supply Module, plug it into the power rails of your breadboard. The module is designed to fit snugly on the breadboard’s power rails, aligning the pins correctly for power distribution. Ensure the module is properly seated to avoid loose connections and inconsistent voltage delivery.

Selecting the Output Voltage

One of the key features of the Elegoo Power Supply Module is the ability to switch between 3.3V and 5V output. This is useful for different types of components that require specific voltages.

Locate the voltage selector switch on the module.

Slide the switch to “3.3V” if your components require 3.3 volts.

Slide it to “5V” if your components require 5 volts.

Always double-check the voltage requirements of your components before powering them to prevent damage.

Powering Your Circuits Safely

Once the module is connected and the output voltage is selected, you can begin powering your circuits. Here are some safety tips to keep in mind:

Avoid Overloading: The module can typically supply up to 700mA of current. Ensure your circuit’s total current draw does not exceed this limit.

Check Connections: Ensure all your circuit connections are secure and free from shorts before powering up.

Use Protective Components: Consider adding fuses or current-limiting resistors to protect sensitive components.

Monitoring Power Status

The Elegoo Power Supply Module includes LED indicators that show the status of the power supply:

Power LED: Lights up when the module is receiving input power.

Voltage LEDs: Indicate which output voltage is selected (3.3V or 5V).

These indicators help you quickly verify that your module is operating correctly.

Troubleshooting Common Issues

If your circuit is not powering up as expected, check the following:

Confirm the power input source is connected and supplying power.

Verify the voltage selector switch is set correctly.

Inspect the breadboard and module connections for loose or misplaced wires.

Ensure you are not exceeding the current capacity of the module.
