The board itself is a slightly updated version of the Orange Pi Zero 2. It features: - Four ARM Cortex-A53 cores, Mali-G31 MP2 GPU - 1/1.5/2/4 GiB LPDDR4 DRAM SKUs (only up to 1GB on the Zero2) - AXP313a PMIC (more capable AXP305 on the Zero2) - Raspberry-Pi-1 compatible GPIO header - extra 13 pin expansion header, exposing pins for 2x USB 2.0 ports - 1 USB 2.0 host port - 1 USB 2.0 type C port (power supply + OTG) - MicroSD slot - on-board 16MiB bootable SPI NOR flash (only 2MB on the Zero2) - 1Gbps Ethernet port (via Motorcomm YT8531 PHY) (RTL8211 on the Zero2) - micro-HDMI port - (yet) unsupported Allwinner WiFi/BT chip Add the devicetree file describing the currently supported features, namely LEDs, SD card, PMIC, SPI flash, USB. Ethernet seems unstable at the moment, though the basic functionality works.
