The board features: - Allwinner A527/T527 SoC: 8 ARM Cortex-A55 cores, Mali-G57 MC1 GPU - 1GiB/2GiB/4GiB LPDDR4 DRAM - AXP717 + AXP323 PMICs - Raspberry-Pi-2 compatible 40pin GPIO header - 1 USB 2.0 type C port (OTG), also power supply - 1 USB 3.0 type A host port (multiplexed with M.2 slot) - 1 M.2 M-key 2230 slot, with 1 PCIe2.1 lane connected (multiplexed with USB 3.0 port) - MicroSD slot - optional eMMC, 8, 16 or 32GB available - optional on-board 16MiB bootable SPI NOR flash - two 1Gbps Ethernet ports (via MAXIO MAE0621A PHYs) - PoE header for optional supply circuit on one Ethernet port - WiFi 802.11 a/b/g/n/ac/ax (LB-Link BL-M8800DS2 module using AIC8800) - HDMI port - camera and LCD connectors - power supply via USB-C connector (but no PD) or GPIO header pins This .dts describes the devices as far as we support them at the moment. The PMIC rails have been assigned as per the schematics.
