I have problem with analog input modul. everything is connected in right way, but when I connect AIN to CORE, main voltage on jumper J2 gets lower from 4.99 to 0.20 volts and display gets dark,  it doesn't depend on how many pots I have connected to AIN, voltage falls even if any pots is connected. When I plug cable into J6,everything works. But when I plug j5 in, voltage gets lower and display gets black. I use MidiBox64 firmware but only one AINX4 module.

sounds like you have a short on the +ive track or something??

have you checked all the tracks for bits of stray solder etc? (use a circuit tester and a magnifying glass  ;)  )

but I dont really know!

Have you got a fuse inline with your power supply?
