I was tested 3 module, all was the same. When input voltage decreased less than 3.2V output voltage was jump up dangerously. For example, when output voltage set to 5V all is nice before input voltage down less 3.2V . When input voltage 3.2V output voltage jump to 15V!!!! And when input voltage decrease less 3.2V output voltage decrease to: 14-13-12-11 and so one.

AlexSk I have no complaints about Banggood. Banggood can not test all the features of each product. Reviews from customers should help in this. My review warns other buyers about the dangerous features of these modules. Perhaps it is necessary to add to the product description that the input voltage should never be less than 3.3V? And that for this reason it is not recommended to use an additional capacitor in the input circuit?
