I'm working around a kind of "universal board" that can be programmed directly from the user.
This board will have 30 lines (2 more lines are used to communicate with the PC) that can be configured as inputs or outputs.
With a software (pc side) the user can decide that 10 of 30 lines, for instance, can be used as inputs, 10 for outputs and 10 to drive a 7 segments display, or 30 only for inputs or only for outputs, or to drive alphanumeric LCD displays, encoders, servos and steppers.
This kind of board should cost less than the other board since it has less components (only 2 chips and some passive component).
I will let you know more about it soon.
