Does anyone have an opto-isolator (board) recommendation for use with Arduino's 5V environment and another circuit at 4.5 volts? I decided I need to isolate the active and power hungry servos.
The optoshield would be your sollution.
It was build by the guys and girls from the forskningsavd in Sweden.
Hi fish_
I wasn't able to find the product although I found the site. Do you have a link?
Thanks,

Well, I couldn't find a shop or pcb lay-out.
But this are some links:
