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 Brent Henderson
GREAT. Do not buy this brand.
This is TERRIBLE! I've tried three so far and all three have been useless. They just pulse on and off. You can't even power the esp8266-01 line. I have successfully used very similar ones from other brands. I don't know if it's a bad batch or a bad supplier. Also other user's advice on changing the solder points didn't work. Just pure garbage.
