1. Introduction
1.1. Overview
Super port module USR-K7 is a new serial Ethernet module. It is a module that can realize
data transmission between the network and TTL serial ports.This module is equipped with ARM
cortex-m4 processor, which has the advantages of low power consumption, fast speed and high
stability.
In terms of volume, the width of the device is equal to the common RJ45 port, and the length
is less than twice the length of the common network port, with the industry-leading ultra-small
volume, and the current is only 130mA when working at full speed.
This product is developed on the basis of the hardware and software of serial to ethernet M4
series.The internal integration of TCP/IP protocol stack, users can use it to complete the embedded
device networking function easily, saving the development process of human, material and
development cycle, so that products can be faster into the market, enhance competitiveness.
This product has been tested rigorously and has been successfully used in Banks, highways,
large corporate networks, busy webcam networks and complex network environments such as
fiber-optic to Ethernet.
1.2 Features
1. New Cortex-M4 kernel, industrial working temperature range(-40~85
℃
), elaborate
optimization TCPIP protocol stack, stable and reliable.
