Breadboard Power Supply Module (3.3V / 5V)

The Breadboard Power Supply Module (3.3V / 5V) is a compact and reliable power supply designed to provide regulated 3.3V DC and 5V DC outputs for standard solderless breadboards. It plugs directly into 400-point and 830-point breadboards, making it an ideal solution for powering electronic prototypes, microcontrollers, sensors, and development modules without the need for complex wiring or external voltage regulators.

The module accepts input power through either a DC barrel jack (6.5V–12V DC) or a USB power input (5V DC), offering flexible powering options for a wide range of electronics projects. It incorporates high-quality voltage regulator ICs to provide stable and low-noise output voltages, ensuring reliable operation of sensitive electronic components and development boards.

Each side of the breadboard power rails can be independently configured to output either 3.3V or 5V using onboard selector jumpers, allowing different voltage levels to be supplied simultaneously to various circuit sections. Built-in power LED indicators provide visual confirmation of the module's operating status, while onboard protection circuitry (model dependent) helps safeguard against short circuits, overcurrent, and incorrect power connections.

The Breadboard Power Supply Module is fully compatible with Arduino, ESP32, ESP8266, Raspberry Pi Pico, STM32, PIC, AVR, 8051, NodeMCU, and other microcontroller development platforms. Its plug-and-play design makes it ideal for rapid circuit development, prototyping, testing, and educational electronics experiments.

The module is widely used in electronics prototyping, embedded system development, IoT projects, robotics, sensor interfacing, educational laboratories, STEM learning, research, and DIY electronics projects. It is an essential accessory for students, hobbyists, makers, engineers, and professionals working with breadboard-based circuits.
