Interface Definition
Ethernet
The board provides one Gigabit Ethernet port using the processor GMAC and an RTL8211F PHY.
Type-C
The full-featured Type-C connector can be used for data transfer. DisplayPort, power direction, and USB role depend on the actual hardware population and software configuration.
HDMI
The carrier board uses a Mini HDMI Type-C connector driven by the native processor HDMI OUT interface.
Micro USB and USB2.0
Micro USB is used for firmware flashing and can also operate as a USB Device interface.
The USB2.0 Type-A Host port supports flash drives, mice, keyboards, and other peripherals.
Audio
Headphone
The headphone output can also feed an external amplifier.
Line Input
The line-input connector accepts external analog audio for recording.
Speaker
| Pin | Signal |
|---|---|
| 1 | LO2 |
| 2 | LO1 |
The board supports a single speaker output of approximately 0.5W.
Digital Microphone
Three digital-microphone resources are routed on the board; MIC2702 is fitted by default.
DC Power and Keys
The hardware specification recommends a 12V / 3A power adapter.
The keys are power, reset, and download from top to bottom.
