MingHe D3806 Boost-Buck converter module

Описание к видео MingHe D3806 Boost-Buck converter module

I got a new MingHe D3806 Boost-Buck converter about a week ago.
It was fine during my first tests but since yesterday I noticed a strange and problematic behaviour. It will give the input voltage straight to the output no matter if the output is activated or not. It will not regulate bellow the input voltage and if you try to boost it it will go 3-4V above the set output voltage.

This was an aliexpress purchase and so far the seller is trying to help. This video is for the manufacturer to note the problem and find a solution.
