MB102 3.3V / 5V Breadboard Power Supply Module (MB102 Breadboard Power Module)

The MB102 3.3V / 5V Breadboard Power Supply Module is a compact regulated power supply designed for standard MB102 solderless breadboards. It provides selectable 3.3V or 5V outputs on two independent power rails, making it ideal for prototyping and testing electronic circuits. The module can be powered from either a DC barrel jack or a USB port and features onboard voltage regulators, a power ON/OFF switch, and a power status LED. It is compatible with Arduino, ESP32, ESP8266, STM32, Raspberry Pi Pico, sensors, and other low-voltage development platforms.
