Overview
Breadboard Power Supply Module – 3.3V / 5V
Make powering your breadboard projects easier with the Breadboard Power Supply Module 3.3V 5V. Designed to plug directly into compatible solderless breadboards, this compact module provides convenient regulated power rails for electronics prototyping without requiring a separate power supply circuit.
The module typically provides selectable 5V and 3.3V outputs, allowing you to power different components according to their voltage requirements. This is especially useful when working with mixed-voltage circuits that include microcontrollers, sensors, displays, logic ICs, and other modules.
It can accept power through commonly used input options such as a DC barrel jack or USB connection, depending on the specific module version. Onboard switches and indicators on compatible versions make it easy to select and monitor the supplied voltage.
Whether you're building an Arduino prototype, ESP32 circuit, sensor system, robotics project, or electronics experiment, this breadboard power module helps keep your prototype wiring organized and simplifies power distribution.

Technical Details
Convenient Breadboard Power Distribution
The Breadboard Power Supply Module 3.3V 5V provides an easy way to supply regulated power to a solderless breadboard. Instead of building a separate voltage regulation circuit, you can install the module directly onto a compatible breadboard and connect your circuit to its power rails.
Dual Voltage Output
One of the main benefits of the module is its ability to provide 3.3V and 5V DC output options.
This makes it useful for projects containing components with different operating-voltage requirements. For example, a prototype may use 5V logic components alongside 3.3V sensors or microcontroller modules.
Select the appropriate voltage before connecting your circuit and make sure every connected component is compatible with the selected supply.
Easy Voltage Selection
Many versions feature onboard voltage-selection switches that allow the user to select the required output rail.
This eliminates the need to repeatedly modify the breadboard wiring when changing between common 3.3V and 5V circuits.
Designed for Solderless Breadboards
The module is designed to sit directly on the power-rail area of compatible solderless breadboards.
Once installed, it provides convenient access to:
- Positive power rail
- Ground rail
- 3.3V supply
- 5V supply
This helps reduce loose wiring and simplifies power distribution during prototyping.
Useful for Arduino and Microcontroller Projects
The module is suitable for powering compatible low-power electronics prototypes involving:
- Arduino boards
- ESP32 projects
- Sensors
- LCD and OLED displays
- Logic ICs
- LEDs
- Small modules
- Switches
- Educational circuits
- DIY electronics
Always check the current requirement and operating voltage of the connected components before powering them.
Multiple Input Options
Depending on the specific version, the module may support power through a DC barrel connector and/or USB input.
This provides flexibility when using a wall adapter, USB power source, or other compatible supply.
Compact Prototyping Solution
The breadboard power module is a practical accessory for an electronics workbench. It reduces the need for external regulator circuits and provides a convenient way to distribute common supply voltages while experimenting with circuits.
Suitable Applications
Use the Breadboard Power Supply Module for:
- Breadboard prototyping
- Arduino projects
- ESP32 projects
- Sensor testing
- IoT prototypes
- Robotics projects
- Logic circuit experiments
- Educational electronics
- LED circuits
- Microcontroller development
- DIY electronics
Important: Do not assume that every breadboard power module can supply high current. The actual maximum current depends on the regulator and module design. Avoid exceeding the module's rated input and output specifications, and verify the selected output voltage before connecting sensitive components.
