I have multiple separate digital units running mainly on Microprocessors/raspberry pi/Arduino with 5V logic. These units are apart and I need them to communicate together. The data lines expected by these units are parallel 64 bits. I need a practical solution to transfer the data between systems for a distance of maximum 10 KM. I expect PISO at one side and SIPO at the order side with cost-effective wiring connecting between the systems or any similar solution.
To summarize the requirements are:
1- Cost Effective Solution.
2- Distance maximum is 10 Kilometers.
3- Circuit Diagram with BOM is required with Digikey/Mouser Part Numbers (NO PCB design required).
4- Suggestion of suitable connector attachable to the PCB and connecting wires specifications.
