Mb102 Breadboard Power Supply Module | Dual 3.3v/5v.

The MB102 Breadboard Power Supply Module is a dedicated dual-voltage regulator board designed to power MB-102 solderless breadboards easily and safely. It provides stable 3.3V and 5V outputs through onboard regulators, ideal for powering Arduino, ESP32, STM32, sensors, and other low-voltage electronic components during prototyping. The module can be powered via USB Type-A or a DC barrel jack (6.5V–12V input) and supports independent voltage selection on both sides of the breadboard, allowing flexible configuration for different circuits.
