Renegade ARM Computer with USB 3 on Android Linux

"Renegade is our first board to feature DDR4 technology, USB 3.0 capability, and Gigabit Ethernet. This modern and powerful platform shares the same form factor as the Raspberry Pi 3 Model B* minus one USB port. It features both mainline Linux and Android 7.1 Nougat Support. Like all of our boards, it is designed completely with open-market components in collaboration with the Firefly team. "

Thanks for posting it RexOr

I forgot, this is also worth checking

Thanks DanBetaMan for the finds. We need some kind of high speed storage interface (SATAIII, M.2, etc.). The Renegade doesn't seem to offer that.

The firefly has a PCIe interface at least but its slightly larger than a NUC as well.

Another interesting bit here, however I am aware is not what we're after...

Hopefully some solution will be found by the time we get the Betas...

looks like we have a bright future ahead on the axiom recorder hardware front.

Thanks @davidak -

The LattePanda 3 Delta should deliver similar performance as the Lattepanda Alpha 864s (that I currently use in the recorder) for around 50% of the price!
