Review on π DAOKI 5 PCS AC DC Power Supply Buck Converter: Step Down Module 12v 5v 3.3v 9v - Efficient Voltage Conversion Solution by Sean Burnett
Reliability sucks
2 stars because only 2 out of 5 boards work. Other pulses are switched on and off even if the DC side is not connected to anything. Even with a 100mA load, they keep switching on and off. To put it mildly, I wasn't impressed. They were bought to make ESP8266 smart sockets. Current draw is minimal as the two I have draw less than 300mA even when transferring and activating the solid state relay so I don't exceed their rating.
- Great for me
- Weight
