The board has the following features: - Allwinner T527 SoC - AXP717B + AXP323 PMICs - Up to 4GB LPDDR4 DRAM - micro SD slot - optional eMMC module - M.2 slot for PCIe 2.0 x1 - 16 MB SPI-NOR flash - 4x USB 2.0 type-A ports (one can be used in gadget mode) - 1x Gigabit ethernet w/ Motorcomm PHY (through yet to be supported GMAC200) - 3.5mm audio jack via internal audio codec - HDMI 2.0 output - eDP, MIPI CSI (2-lane and 4-lane) and MIPI DSI (4-lane) connectors - USB type-C port purely for power - AP6256 (Broadcom BCM4345) WiFi 5.0 + BT 5.0 - unsoldered headers for ADC and an additional USB 2.0 host port - 40-pin GPIO header Add a device tree for it, enabling all peripherals currently supported.
