Hi 
I've spun up an expansion board to expose the linux uarts on the legacy and high speed headers for the Voxl2 as well as give a usb2 interface. 
Would you be willing to review it? I'd buy a board that exposed these ports if it existed, but I haven't found a board that exposes USB2 (or USB3) as well as the three linux UARTs.
cheers
Peter

@Peter-Milani 
However, I am on vacation for a week starting in a few hours.
So, I will get to the review the week of 8/4 when I return (just to set expectations).
Thanks!
