DIYables Breadboard Power Supply Module for Solderless Breadboard
Click to zoom
Quick Overview
The DIYables breadboard power supply module provides convenient 3.3V and 5V power outputs for solderless breadboard projects. It plugs directly onto the breadboard and delivers regulated power to both rails, making it easy to power multiple components at different voltages.
The module accepts input from either a DC barrel jack (7-12V) or USB power supply (5V). Jumpers allow you to select whether each breadboard rail receives 3.3V or 5V, providing flexibility for mixed-voltage circuits common in Arduino, ESP32, and other microcontroller projects.
Key Features
- Dual Output Voltages — Simultaneous 3.3V and 5V outputs from onboard jumpers
- Selectable Rail Voltage — Choose 3.3V or 5V for each breadboard power rail via jumpers
- Dual Input Options — Accepts 7-12V DC barrel jack or 5V USB power
- Direct Breadboard Mount — Plugs directly onto solderless breadboard
- 700mA Output Current — Sufficient for most microcontroller and sensor projects
- LED Indicator — Power status LED for visual confirmation
