Breadboard Power Supply Module for MB-102 – Selectable 3.3V / 5V Dual Output for Electronics Prototyping

🛠️ Breadboard Power Supply Module for MB-102 – Selectable 3.3V / 5V Dual Output for Electronics Prototyping

This Breadboard Power Supply Module is designed to conveniently deliver 3.3V or 5V regulated output to MB-102 breadboards and other compatible models. It is an essential accessory for Arduino, ESP32, Raspberry Pi, STM32, and other microcontroller-based prototyping projects, providing stable and selectable voltage rails for your experiments.

The module accepts standard DC barrel jack input (6.5V – 12V) or USB power via Mini-USB port and outputs regulated voltage to the breadboard’s power rails (left and right sides independently selectable between 3.3V and 5V). This flexibility allows for powering components that require different voltage levels simultaneously.
