Re: 8 Battery Lead Acid Slave Board

Ideas,
First I thought of joining a master board to the slave board (physically, not electrically) and routing grooves between them, simply snapping to separate. This would mean that I don't pay pcb cart the "one off tooling fee" twice, which would be cheaper.
Then I thought perhaps combining a master and slave into a single board (connected through optocoupler) would help reduce the length and number of interconnections. Two black boxes instead of three, just populate the bits you need. I was planning to optoisolate the buttons and speed sensor on the master anyway. Any thoughts? Interference nightmare?
