Detailed Description:

Simplify your electronic prototyping and ensure stable power delivery with our indispensable Breadboard Power Supply Module – Dual 3.3V/5V Regulated Power. This compact and highly efficient module is designed to plug directly into your standard solderless breadboard (commonly compatible with MB102 type breadboards), providing a clean, reliable, and convenient power source for all your circuits.

Gone are the days of messy wiring from external power supplies or relying on your microcontroller's limited onboard voltage regulator. This breadboard power supply module eliminates clutter and simplifies power distribution by integrating voltage regulation directly onto your breadboard. It typically accepts input power via a DC barrel jack (6.5V to 12V DC) from a wall adapter or a 9V battery, and often includes a micro-USB port for convenient power input from a computer or USB charger.

The core functionality lies in its dual regulated outputs of 3.3V and 5V DC. This is crucial because many microcontrollers (like Arduino Uno at 5V, ESP32/ESP8266 at 3.3V), sensors, and modules operate at these specific voltage levels. Key features include:

• Selectable Output Voltage: Most modules allow you to independently select either 3.3V or 5V for each power rail of your breadboard using jumper pins. This flexibility means you can power different sections of your circuit with different voltages simultaneously.

• Integrated ON/OFF Switch: A convenient onboard switch allows you to easily power your circuit on or off without needing to unplug the power source.

• LED Power Indicator: A small LED (usually green or red) provides immediate visual confirmation that the module is powered on.

• Voltage Regulators: Utilizes reliable low-dropout (LDO) voltage regulators (such as AMS1117-3.3 and AMS1117-5.0) to ensure stable and consistent output voltages, protecting your delicate electronic components from fluctuations and spikes.

• High Current Capacity: Typically capable of supplying up to 700mA or even 1A per rail, sufficient for powering a wide range of components including LEDs, sensors, small motors, and microcontrollers.

This breadboard power supply module is an essential tool for:

• Arduino & Microcontroller Prototyping: Providing dedicated power rails for your development board and peripheral components.

• DIY Electronics Projects: Simplifying the power setup for all your custom circuits.

• Sensor & Module Testing: Ensuring stable power for accurate readings during testing phases.

• Educational Environments: Ideal for students learning about basic electronics, circuits, and power management.

Invest in a cleaner, safer, and more efficient prototyping experience.

The Breadboard Power Supply Module is a compact voltage regulation board that provides 3.3V and 5V DC outputs, ideal for powering microcontrollers, sensors, modules, and LEDs on a solderless breadboard.

It features a dual output regulator selectable via jumper caps and supports input from a USB port or 6.5V–12V DC adapter through a barrel jack. Both sides of the breadboard can be powered independently in 3.3V or 5V mode, making it extremely versatile for prototyping.
