NIM defect? <<<<SOLVED>>>>
Posted: Tue 21 Jan 2020 12:33
yesterday I received the MiniTiounerPro V2 set.
Today I checked the Voltages on the PCB 3,3V and 1,1V. Everything was OK, the current consumption is 32mA.
After put in the NIM the current consumption was going on 500mA. I used a power supply with current limiting which was set by 500mA. The Voltage was breaking down from 12V to 3.2V. This all means the NIM is defect, there is somewhere a short-circuit.
I was looking in the NIM, but nothing is to find.
Now I think I need a new NIM.
Or someone has other suggestions?
