Ethernet interface

3.6.1

Introduction

The development board has two Ethernet circuits and supports gigabit

mode, which can be used to test hardware environment in the LED display
applications, and Ethernet data transmission. The interface connected to
other devices is RJ45 with the built-in transformer. The connection diagram
is as follows:
