What is the MB102 Breadboard Power Supply Module?
The SHILLEHTEK Universal Power Supply Module for MB102 Breadboards is a convenient and reliable way to power your prototyping projects. Supporting both 3.3V and 5V outputs, it is compatible with DC input (6.5V–12V) and USB power, allowing flexible connectivity for Arduino, Raspberry Pi, ESP32, and other microcontroller-based projects. Designed specifically for solderless breadboards, this module simplifies power distribution during testing and development.
Operating Mechanisms of the MB102 Power Supply
The MB102 module regulates input voltage to selectable 3.3V or 5V outputs, providing power to both power rails on your breadboard. Here's how it works:
- Dual Voltage Output: Independent selection switches allow each rail to be set to either 3.3V or 5V, offering flexibility depending on your component requirements.
- Power Input Options: Accepts DC input via a barrel jack (6.5V to 12V) or USB, making it easy to connect to wall adapters or power banks.
- Breadboard Compatibility: Designed to slot directly into standard MB102 solderless breadboards, powering both side rails cleanly.
- On/Off Switch: Allows quick power toggling without disconnecting cables.
This module is ideal for rapid prototyping, educational setups, and DIY electronics builds where clean and selectable voltage regulation is essential.
