This week we received the adapter board so that the KVM switch could be easily stacked on top of the Pi-Cast. The adapter board also supports PoE ethernet and a fan for the Pi-Cast.

 In the prev design, we use the gpio to control the switch, but in the new version we've added another control method call serial control, you can control the switch by the USB-to-Serial port. The control protocol is compatible with the EZCOO.
