Lonely Binary 3-Pack Breadboard Power Supply 3.3V 5V USB-C Switchable

Key features

• 3.3V/5V SWITCHABLE OUTPUTToggle between 3.3V and 5V with a slide switch, up to 500mA per module (PPTC protected) — for powering 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.

" Lonely Binary 3-Pack Breadboard Power Supply Modules The Lonely Binary Breadboard Power Supply Module is a compact power adapter for electronics prototyping on solderless breadboards. This 3-pack plugs directly into the power rails of your breadboard (sold separately) to provide voltage for your circuits, reducing wiring and external adapters. Suitable for hobbyists, students, and makers working on prototypes, testing, or STEM projects with boards like Raspberry Pi, Pico W, and ESP32. Key Features Switchable Voltage Outputs:Select between 3.3V and 5V with a slide switch. Built-in 500mA PPTC fuses for overload protection. Type-C Input:USB Type-C port for power from any 5V source, such as laptops or hubs. Safety and Convenience:Resettable fuses protect components; LED indicators (red for 5V, blue for 3.3V) for status monitoring. Install on the correct end of the breadboard for proper polarity. Compatibility:Works with ESP32 development boards, sensors, LEDs, and other digital/analog projects. Specifications Output Voltage: 3.3V / 5V (switchable) Output Current: up to 500mA per module (PPTC resettable fuse protected) Measured Output: approximately 3.27V (3.3V setting) and 4.92V (5
