The problem with DSO138 Kit
Posted: Sat Feb 04, 2017 2:20 pm
I bought and soldered DSO138 Kit, but after assembling there is a problem.
As described in the instructions to check the voltage 3.3 volt - JP4 jumper is not soldered.
The inspection revealed that the transistor Q1 (s8550) is strongly heated up and burned.
Why is there this problem?
It's a original or fake dso138 kit?
