4 Interface and signal description
4.1 Fast Ethernet LAN
The LAN1 and the LAN2 connector support 10 and 100 Mbit LAN.
4.2
USB host
The single USB Host connector does support USB2.0 connection with high speed up to
480Mbit/s and also full and low speed devices.
The power on the 5V line is equipped with a resettable fuse with 500mA.
4.3 USB device
The USB device connects the armStoneA5 as device on a PC.
4.4 microSD
The microSD push-push connector supports the SD Standard Host Specification Version 2.0 standard.

4.5 LVDS port connector
The single channel LVDS display port can be direct connected to a LVDS 18 bit display.
The VLCD voltage is 3.3V and switched on the baseboard. The current limit is 1.2 A.
Connector is a JAE FI-S25P-HFE. Matching connector on display cable is a crimp connector
FI-S25S housing and a cable with FI-C3-A1-15000 crimp contacts.
This connector is used because a wide range of displays does have a JAE FI-S series connector (with different pinouts) and it's easy to handle identical crimp contacts for the cable manufacturer.

5.4 Shield to GND connection
There is the possibility to add a shield ground to signal ground connection on both mounting holes on front side. There are 0603 shapes on the solder side of the board to add a connection. This gives customers the possibility to change EMV characteristic. On default this parts are not mounted and the shield ground is not connected to the signal ground.
