Re: Changes from Pi 2
On the underside there is a very curious white connector/header with 8(?) tracks going to it. It's below the HDMI connector when looking sideways on. So could that be some kind of SATA or other serial interface?
It seems the Wi-Fi connects to the SoC using an SDIO bus, which I would guess is why it's still four USB 2.0 ports + 10/100 LAN same as on earlier versions. I would expect the Bluetooth controller also attaches to the same SDIO bus and my guess would be this is a connector for additional, external SDIO devices.
