5V 1A Power Supply Board 220V AC to 5V DC

The circuit produces an output of 5V and 1A, it is mainly used in cell phone chargers, microcontrollers, Bluetooth/WiFi modules and in any DIY projects that can be operated via 5VDC. The module has a power rating of 3W.. The circuit board converts an input voltage of 220V AC and converts it into a 5V DC output. The circuit has a transformer that steps down the voltage from 220V AC to 5V AC, The four diodes in the circuit act as a rectifier that converts the AC voltage to DC voltage.
