Interface Details

This page organizes the interfaces by function for wiring, driver debugging, and documentation reuse.

mini PCIe

Used for a 4G wireless communication module together with the SIM slot.

TF Card

On-board TF card slot for external storage or upgrade use cases.

UART

UART6 and UART4 are RS485-level interfaces and can be configured as TTL. UART3 and UART0 are RS232-level interfaces. UART5 and UART7 are TTL. UART2 is the default debug UART.

USB

The board provides multiple USB HOST2.0 ports, a stacked USB host connector, USB HOST3.0, and Type-C. Type-C can be used for firmware download.

Display

HDMI OUT, VGA, DSI0, DSI1, and EDP are available. EDP is shared with HDMI OUT.

Audio

LINE IN, headphone output, MIC input, speaker output, and HDMI audio output are supported.

Network

GMAC is the Gigabit Ethernet interface. The board also includes dual-band Wi-Fi/Bluetooth and supports mini PCIe wireless expansion.

SATA

SATA power and signal connectors are provided for SATA SSD/HDD expansion.

Camera

MIPI CSI0, CSI1, and CSI2 camera connectors are available. The board supports up to four CSI cameras.

Keys and Expansion Signals

Volume up/down, boot, reset, PWRKEY, power control, recovery, update, and GPIO expansion signals are exported.

Power

DC jack, 12V IN, 12V OUT, and fan power connector are provided. 12V OUT and fan power can be GPIO-controlled.

RTC

The coin-cell battery keeps the RTC running after main power is removed.
