About this product
The HLK-10M05B from Hi-Link is an AC-DC module that converts 220Vac mains input into a 5Vdc output rated at 2A (10W). It is intended for powering microcontroller boards, sensors and small electronic circuits directly from the mains without a separate adapter. Because the input is mains voltage, it should be installed in an insulated enclosure.

Frequently asked questions
Can I use this module to power an Arduino Uno directly?
The output is 5Vdc at up to 2A, so it can supply a 5V board. Connect the module's 5V output to the board's 5V pin and its ground to GND, and keep the mains side fully insulated.
Is this module suitable for direct mains wiring by a beginner?
The input side carries 220Vac mains, which is dangerous. Make all mains connections with the power off, use an insulated enclosure, and verify the output with a multimeter before connecting any load.
