This isolated AC-DC module converts 220V mains directly to a regulated 5V DC rail, delivering up to 700mA — enough to power a microcontroller, a handful of sensors, or a small relay board straight off wall power without a separate wall-wart adapter. Galvanic isolation between the AC and DC sides adds a real safety margin and cuts down on mains-induced noise reaching sensitive logic circuits.
The compact SMPS design solders directly onto a custom PCB, making it a practical building block for enclosed mains-powered projects — smart switches, automation panels, or IoT devices — where a bulky external adapter isn't an option. It works cleanly with Arduino, ESP32, and Raspberry Pi peripheral circuits.
