Neat! Pledged for 1 to play with it... If this gets support, it could be what Shield was intended to be.
And if it doesn't, you can still use if for Plex Media Server or other fun projects.
With the GPIOs on it, you also have the opportunity to add other wireless networks, like Z-wave,LoRA etc to control domotica.
Using Shield Pro v1, Chaos Calmer, FW 1.51 SP1, Bridge Mode
