I don't have any interface and I want to build it myself.
I believe that an interface based in 18F2450; 18F2455; 18F2550; 18F4450; 18F4455; 18F4550 are better. The interfaces based on 16C745 and 16C765 are OTP
That interface is better?? Where the pcb is??
Excuse my poor english. I'm spanish.
Thank you.
