The MB102 Breadboard Power Supply Module is a convenient and reliable power solution for electronics prototyping, Arduino projects, embedded systems development, and breadboard-based circuit testing. Designed specifically for MB102 breadboards, this module provides stable 3.3V and 5V regulated outputs, making it ideal for powering microcontrollers, sensors, modules, and other electronic components.

Featuring dual independent power rails, the MB102 power supply allows each breadboard rail to be configured separately for 0V, 3.3V, or 5V using onboard jumpers. The module supports power input through either a DC barrel jack or Micro USB port, offering flexible power options for different project requirements.

Its compact design, onboard power switch, LED status indicator, and additional output pins make it one of the most popular breadboard power modules for students, hobbyists, engineers, and makers in Bangladesh.
