The Breadboard Power Supply Module (MB102) provides a convenient way to power your breadboard projects with stable 3.3V or 5V outputs. Designed to plug directly into standard MB102 breadboards, this module distributes power to both sides of the breadboard rails, eliminating the need for complex wiring or external regulators. It can be powered via USB or DC barrel jack, making it flexible for both bench testing and portable projects. Each power rail can be independently configured to 3.3V, 5V, or turned off, allowing you to power different parts of your circuit safely. Built in voltage regulators ensure stable output, making it ideal for microcontrollers, sensors, and other low voltage electronics. This module is widely used in Arduino prototyping, electronics labs, robotics builds, and STEM education setups, where reliable and easy breadboard power is essential. Highlights: Dual Voltage Output: Provides selectable 3.3V or 5V power rails. Independent Rail Control: Each breadboard rail can be set to 3.3V, 5V, or OFF using onboard switches. Multiple Power Inputs: Can be powered via USB or DC barrel jack (7-10V). Breadboard Friendly Design: Plugs directly into standard MB102 breadboards for quick setup. Stable Voltage Regulation: Onboard regulators ensure consistent power for sensitive electronics. Specifications: Input Voltage (DC Jack): 7-10V. USB Input Voltage: 5V. Output Voltage: 3.3V / 5V selectable. Maximum Output Current: up to 700mA (depending on input and regulator). Power Inputs: USB Type A / DC Barrel Jack.
