This +could have been useful when putting such a combination of boards in a case +designed for stacks of Arduino boards and shields, since there is otherwise +not enough space between the female headers of the Arduino board and the +underside of this board to be able to use jumper wires, as had been intended. +However, breadboard jumper cables can be used to route the signals between the +boards. + +Another potential change could involve the positioning of the VGA output +connectors, these having been situated at the opposite end of the board to +where an Arduino would have its USB and power connectors. It might have been +more sensible to have put the VGA connectors, these being external, on the +same end as the Arduino's own external connectors, with the programming pins +either being routed via stackable header connections or through connectors on +the end of the board that would be internal within any case or housing. + +Despite the above Arduino-related suggestions, this board was not designed as +an Arduino shield, needing rather more flexibility in terms of providing +connections of specific kinds, and although the intention was to make use of +Arduino-compatible cases or housings, it was never envisaged that any +particular case would be completely compatible with this board. + Design Rules and Production ===========================
