The board has: H616 SoC 1GB of RAM AXP313A PMIC And the actual boards that CB1 plugs in are just extension to it with ports and thus are not split in DT. Boards have: 4x (3x for Manta boards) USB and 1 USB OTG. SDcard slot for loading images. Ethernet port wired to the internal PHY. 2x HDMI 2.0. Power and Status LEDs.
