View Full Version : Requirements on a break out board?

Hi all,
I'm a bit confused as to what the minimum requirements are on a break out board. My planned system is a PC with LinuxCNC, BOB, drivers and stepper motors.

Take this for instance:
Obviously there are no opto couplers to protect the computer. But is anything else needed for comunicating with the stepper drivers?

From my experience a breakout board is simply a extension of the connecting port which makes it easier to connect the wires. I would have thought opto couplers would be a high priority though.

Try doing a search on the forum, someone asked a question like this not that long ago & there were some good explanations given.

This is the one that I have bought CNC4PC (http://www.cnc4pc.com/Store/osc/product_info.php?cPath=33&products_id=425) as the one that was supplied for free with the drivers I found would not work well with the pp. This one worked staight out of the box and is independant and isolated from the pp.
