Changinng the microcontroller with a CAN one (for those interested) is the answer. > So maybe you could just > provide a small header with TXCAN, RXCAN, and maybe +5 and ground?

DB9 is too big at this point, however it can be used, there isn't any RS232 onboard, except the USB/RS232 interface. > The RJ10 (4P4C) is also popular.

This board started as a collection of interfaces connected as a sandwich to a core, carrying the microcontroller. When every interface works I've decided that structure it's a mistake, mostly because of the large numbers of connectors. Then I need a dataloger and a battery was added. This one is using a lot of space. As a factory manufactured board this is not very crowdy at all.
