Lonely Binary 3-Pack Breadboard Power Supply 3.3V 5V USB-C Switchable | 3.3V /5V slide switch, 500mA PPTC protection; USB-C 5V input; dual LED indicators; plugs into breadboard power rails

Features

• 3.3V/5V SWITCHABLE OUTPUTToggle between 3.3V and 5V with a slide switch, up to 500mA per module (PPTC protected) for powering Arduino, Raspberry Pi, Pico W, ESP32, and other microcontrollers without extra adapters.
• BUILT-IN SAFETY PROTECTIONPPTC resettable fuses limit current to 500mA per module to help prevent overloads and short circuits suitable for beginners and experienced makers working on STEM projects.
• USB TYPE-C CONNECTIVITYUSB Type-C input (5V DC) for power from laptops, power banks, or USB hubs reduces wiring for portable prototyping setups.
• LED POWER INDICATORSDual LEDs (red for 5V, blue for 3.3V) show active voltage status for safe operation and quick troubleshooting during DIY builds.
• COMPACT 3-PACK, FOR LOW-POWER LOADSPlugs directly into standard solderless breadboard power rails. Suitable for logic circuits, sensors, displays, and single dev boards (up to 500mA). For high-current loads like motors or large LED arrays, use a dedicated supply. Pack of 3. Note orientation to avoid reversed polarity.
• RELIABLE VOLTAGE STABILITYMeasured outputs of ~3.27V (3.3V nominal) and ~4.92V (5V nominal) with minimal drop; great for quick prototypes, though note orientation to avoid reversed polarity.
