This controller has value-added in integration, packaging, input protection and such. They have done things we will not have to ourselves. We looked at Beagles but want to avoid the issues with supporting a Linux device.

I've not found an Arduino case/touchscreen/AD/input protection/ etc that we can plug in and fly with.
