Product Overview
The MB102 breadboard power supply module is designed to provide stable regulated 3.3 V and 5 V DC outputs directly to a standard MB102 breadboard. It can be powered using a 7 V to 12 V DC adapter through the DC jack or via USB input. The onboard voltage regulators ensure stable output for microcontroller and sensor projects. Each side of the breadboard can be independently configured to output either 3.3 V or 5 V using jumper selection.
This module is suitable for Arduino development electronics prototyping and automation testing setups.

Installation Notes
Insert the module into the MB102 breadboard power rails. Select the desired output voltage using the jumpers before powering the circuit. Use either a 7 V to 12 V DC adapter or USB input but do not connect both power sources at the same time. Ensure correct voltage selection before connecting sensitive components.
