Hi Christof,
I apologize, I called James and he was unavailable at the time. I went on vacation and forgot all about it.
I called again today and James was out but talked to Jeff who said it's at 300hz now but James has had it running at 500 hz for a while and just needs a little more testing before it would be released. The code is easily upgraded so not a big deal.
I am still willing to go in on purchasing a VN-100 board but have other plans for it's use. I see value in the VN-100 in a commercial platform because of it's easy replacement if the IMU fails. I doubt if we will see any major improvement in performance over a correctly calibrated AQ.
Is it worth $800 to not have to calibrate your AQ?
