Looking for the most petite (manufactured/assembled) power supply 220V to 5V (not less than 300 mA) for microcontroller. While staying at option 1
and option 2 (HLK-PM01)
. The question is in reliability. Is it worth it to use these power supplies for continuous operation the microcontroller + sensors (plug and forget for six months or a year). What other ready-made options with minimum dimensions can be considered for such purposes?
