Sir,
I am an experienced electronics engineer in a leading electronics company.
I developed so many Raspberry Pi projects, Embedded boards, FPGA boards, SoC boards, Microcontroller boards using ORCAD Cadence and written codes in C, VHDL, Vivado.
I will do this project first on Raspberry Pi board. Then i will design fresh schematic for your application, and design PCB board as per your space constraints, then i will give you BOM and gerber.
I will also give you detailed procedure on how to integrate whole system.
Total Budget of this project is 2000$.
Thanks
