RP-H6B is their official evaluation board of RP-H6C, with an onboard GL850G USB hub, Ampak AP6212 Wi-Fi module and some circuits about LVDS display. It also exports the OTG USB port, the USB 3.0 port, PCIe bus (as mPCIe slot), internal Ethernet PHY, analog audio/video and HDMI port. Add a DTSI file for the SoM and a DTS for the full board.
