Please let me know if this is not the proper forum for this question and if not then please kindly redirect me. I've done my best to search for an answer to my question but have after 5+ hours not found an answer.
I'm new to RPi but have worked extensively with Arduino (ATmega2560). My Arduino project code is complete: It controls a rather large machine comprised of a dozen stepper/DC motors and a number of sensors and what not. The ATmega2560 has gobs of IO.......but the RPi does not. While my Arduino board has satisfactory IO it does not posses higher level functionality that I need: things like Wifi, cron, SSH, etc.
I've considered the many posts on using the Arduino as a slave to the RPi but for various reasons I won't go into here, I really would rather not go that route unless I have to and so my question is as follows:
Are there GPIO expansion boards out there (other than the one below) and does anyone have any recommendations for such GPIO expansion boards? I found this one http://www.amazon.com/gp/product/B00YXH ... APE4CAYC9P but after reading the doc I don't get a warm fuzzy. Most of my IO need is for writing/output. I wish to know if there are other options for expanding GPIO?
Thank you, Keith

And the following looks to be the same board but different constructor as in your initial post:
