I have observed the address lines holding at 1.5v on a regular cart too. The MDII doesn't display the same behavior.

I'm sending this out during this week to a PCB fab, just need to do second review.

Board is 2-Layer and all components are on top side. Passives are 0402 which could be tricky for hand soldering (I'm able to do it fine)
SD Card was changed to micro due to space constraints.

I'll report again soon
