As I mentioned in a previous post, it is not always easy to arbitrate between the capacities of a system and the difficulty of its material realization, especially if in addition the final price must be as tight as possible.
For this uPF--2 I considered several possibilities before arriving at a system which I believe to be sufficiently simple but efficient for the envisaged use.
Here in 3D what should look like the system :
Due to the FPGA used, I reduced the expansion bus to only addressing peripherals. This should be more than enough to create I / O expansion boards of all kinds.
This system takes all the characteristics of the original board of Wichit Schirichotte, but largely improved in terms of capacities and speed of execution.
