Hi-Link HLK-PM01 AC-DC Power Supply Module – 100-240V to 5V 600mA 3W

Hi-Link HLK-PM01 AC-DC Power Supply Module – 100-240V to 5V 600mA 3W

The Hi-Link HLK-PM01 is a compact, isolated AC-DC switching power supply module that converts mains voltage (100-240VAC) directly to a stable 5V DC output. Encapsulated in a robust black epoxy housing, it's the go-to solution for powering ESP8266, ESP32, Arduino, and other 5V microcontroller projects directly from the mains — without a bulky external adapter.

CE certified and widely trusted in the maker and IoT community, the HLK-PM01 simplifies embedded power supply design with its plug-and-play form factor and universal input voltage range.
