  • Good quality but pay attention to output voltage

    Pros: good quality, it works well
    Cons: output voltage is 5V. Normally this adapter is used to program ESP8266 boards which are 3.3V. There's a switch in the board with some writing 5V in one side and 3.3V in the other BUT IT HAS NO EFFECT as the output remains 5V no matter the position of the switch.
    If you want to use with ESP8266, be sure you have a 5V to 3.3V converter (level shifting module) at hand. I used SKU 308899 from DX and it works perfectly.
