Erle-Brain 2 (not yet released) looks suspiciously like a Navio+RPi2 in a box.
It’d have to be a lot fatter than that if it’s really got a RasPi2 inside (as anyone who’s 3D printed a case will know). Probably be twice as expensive too like the first one
At least the pins are 90° inverted.
It is not Navio+, but smart move for them to go with Raspberry Pi 2.
