6.5 USB_HOST connectors

The part of the schematic related to the USB_HOST connectors is listed below:

There are two USB host connector featured on the board. They are called USB_HOST1 and 
USB_HOST2. Each of them has own connector, both situated near the Ethernet connector. Each of 
connector has own low loss power distribution switch SY6280 which protects the board in case the 
devices you have plugged to the board try to draw more current than 523mA combined. The 
maximum current available on each of the USB hosts is exactly 523mA.

The SY6280 responsible for the USB_HOST1 is enabled by USB0-DRV1 (processor pin A4).

The SY6280 responsible for the USB_HOST2 is enabled by USB0-DRV2 (processor pin A5).

6.6 Ethernet

The LIME board is equipped with a standard RJ45 Ethernet connector at the top of the board that 
allows you to access local network via an Ethernet cable.

The LAN connectivity is handled by Realtek's RTL8201CP. Some of the features of this 
10/100Mbit controller are:
