Too much time without posting anything new about this project, by now, I decided to make a PCB in order to allocate the processor and some other stuff (FTDI2232H and a modbus LTC485 driver)
Two sides board, with standard rules to send the pcb to PCB-CART in order to produce 3 units for testing purposes.
The next step will be to mount ans solder the components and take a long or short time (depending on my efficiency) in order to test the hardware and the software.
This pcb will be intended to use as main board, that is why I have routed all the I/O pins to the side connectors , and then other expansion boards could be connected
If someone is interested in the pcb project file I could provide it too.
