Ok, let me try again, without these less important differences:

As this problem is to be taken care of on the Housing it is worth observing that CPU Cards do not need to perform UART buffering (as this would interfere with their potential use as GPIO lines).

i realised that the reason *why* you don't level-shift on the Card was not mentioned.
