| 3 | GND |
| 4 | GND |
Use a 12 V / 3 A supply. RESET resets the board, FEL enters the Allwinner flashing mode, and POWER controls power/suspend/wakeup behavior.
USB, network and expansion
- Type-C is the OTG/Device port used for PhoenixSuit flashing and ADB.
- One USB 3.0 Host and two USB 2.0 Host ports are available.
- RTL8211F provides Gigabit Ethernet over RGMII.
- The PCIe/SIM connector supports a 4G module.
- TF and M.2 provide storage expansion; verify the M.2 key/protocol against the schematic and BOM.
HDMI OUT is native to the SoC. HDMI IN is converted by LT6911C to a MIPI CSI stream.
