Three Pack Breadboard Power Supply Modules 3.3V And 5V USB C Output Switchable With Overcurrent Protection For Arduino Raspberry Pi Pico W ESP32 And Other DIY Gearheads Prototyping Tools Breadboards Not Included

Three-Pack Breadboard Power Supply Modules: 3.3V/5V
✔️ Switchable 3.3V/5V output, USB-C, 500mA PPTC fuses

The three-module breadboard power supply set provides stable 3.3V or 5V rails for quick prototyping on breadboards. Each unit plugs directly into the power rails, making it easy to power Arduino, Raspberry Pi Pico W, ESP32, and other hobby boards without extra adapters.

✅ Switchable outputs: 3.3V up to 1A and 5V up to 1.5A via a slide switch
✅ Overcurrent protection: PPTC resettable fuses limit to 500mA per module
✅ USB Type-C input/output: 5V DC supply from laptops, hubs, or power banks
✅ Status LEDs: red for 5V, blue for 3.3V for quick status checks
✅ Easy breadboard integration: plugs directly into breadboard rails; pack of 3
✅ Measured stability: tight tolerance with small voltage drop during load, ensures safe prototyping
✅ Orientation note: install on the correct end to avoid polarity reversal
