1.4.6
Gigabit Ethernet
The IEEE802.3 compliant ethernet supports 10/100/1000Mb half-duplex and full-duplex auto-
negotiation. The GbE communicates to an external PHY, RTL8211F-CG, through an RGMII
interface from the processor. The RJ45 connector contains status and speed lights. The green
light is on for connected and flashing for data transmitting. The yellow light is on for 1000Mbps
and off for 10/100Mbps.
1.4.7
Power Input
Power Delivery (PD)
The power port uses a USB-C port, which supports USB PD 3.0 . An on-board Power Delivery
controller allows the maximum power input of 20V @ 3A. The Edge 2, as device mode, can be
communicated by USB-C, which supports USB 2.0 for ADB debugging, firmware update.
12V DC
DC power inputs from a DC power jack socket or a SATA power socket require 12V @ 3A.
1.4.8
USB 2.0/3.0 Host Ports
Edge 2 has three standard USB 2.0/3.0 host ports using type-A connectors and one USB 2.0/3.0
port connects M.2 socket. These USB 2.0/3.0 ports are provided by a USB 3.0 hub, VL817. The
three type-A connectors support 5V at 1A power and dependent software power dis/enabling.
1.4.9
RS485
RS485 connector has three pins, pin A, B, and GND for communication. RS485 connects to
UART4
in CPU via interface IC, SP485REN-L. RS485 is a half-duplex bus with a default setting on
receiving state. It will automatically switch to the sending state when needed. RS485 uses full
isolation designs, the power supply and ground are isolated from the module used in the board,
and the signal is isolated by an optocoupler.
1.4.10
Display Support
The video output processor supports the resolution from 1920x1080@60Hz to 4096x2304@60Hz
and three simultaneous displays in the following interfaces. The default main display is HDMI.
HDMI
HDMI display compliant HDMI 1.4 and HDMI 2.0. It supports up to 1920x1080@120Hz and
4096x2304@60Hz resolution.
eDP
The eDP display supports up to 2560x1600@60Hz resolution, up to 4 lanes of 2.7Gbps/lane.
The 30-pin FPC connector includes the eDP interface and a backlight source. The pin
assignments are listed in the next chapter.
