I have troubles to get my Matrix work with Raspberry Pi Zero W (5,1V 2,5A power supply). I have tried packages reinstall/updgrades also did the hardware test. I am asking for help with investigating, there seem to be a hardware problem. I have checked pins on Raspberry with multimeter and they are fine.
