Breadboard power supply

Compact, Reliable Breadboard Power Supply – 5 V to 12 V, 2 A

This compact, fully isolated switching power supply delivers stable, low‑noise DC for prototype boards and hobbyist projects. Its adjustable output (5 V–12 V) and 2 A current limit make it ideal for a wide range of low‑power circuits, from microcontroller demos to sensor arrays. The supply features a high‑efficiency pulse‑width‑modulated regulator, 1 V ripple, and an over‑current protection that holds over 9 W dissipation in a 70 mm×30 mm chassis. A clear front‑panel with LED indicators and a 3‑pin JST terminal block allows rapid, low‑risk connections to any breadboard.

• Key Spec 1: Output range – 5 V to 12 V with ±1 % regulation
• Key Spec 2: Current limit – 2 A, fuses automatically reset after power cycle
• Key Spec 3: Switching frequency – 100 kHz, resulting in <1 V peak‑to‑peak ripple
• Common Use Case: Ideal for powering microcontroller prototyping, sensor testbeds, and low‑power audio circuits directly from a breadboard.
