Dear Paul
you have been a gr8 help and really helped me with a lot of info which i didnt know of.
For now I have decided to work with the components that I have mentioned for the prototype (since it is a project and not final product). I will forget about space and size issue right now. if the components with the correct coding are successful, then I can have a PCB designer specifically design a PCB with the specifications i need (removing unnecessary items) and have it produced, this way it will be smaller in size and im sure way much cheaper.
what do you think?
below are some website that can fabricate the PCB we want:-
any other advice from you, plz do share.
Thanks and regards
