New Solenoid Breakout Board?

I was browsing the Andy Mark website today and noticed a new Solenoid Breakout board. Do we have to purchase this to use on the robot this year? We haven’t used pneumatics since 2008, and we have the boards from the 2009 kit still (revision 3). Should we get the new Revision 4 board or will these work the same?

So far, board updates haven’t changed functionality, they’ve only made things more robust. If it ain’t broke, don’t replace it. If it broke, replace it with a newer model and it will last longer.

Thank you! This will save us about 50 dollars.
