Chapter 1 Overview
1.1 Introduction
E103-W03 is an ultra-low power serial port to Wi-Fi module, SMD small-volume
package, PCB antenna, working in the 2.4~2.484GHz frequency band. The module
can use the serial port to send and receive data, lowering the threshold of wireless
applications.
The E103-W03 module is developed by Chengdu Ebyte Electronic Technology Co.,
Ltd. based on TI's CC3220R chip. The module integrates the transparent
transmission function, which can be used out of the box and supports the serial port
AT command set. Users can use the network access function through the serial port. It is widely used in wearable devices,
home automation, home security, personal health care, smart home appliances, accessories and remote controls,
automotive, lighting, industrial Internet and other fields.
E103-W03 module supports standard IEEE802.11b/g/n protocol and complete TCP/IP protocol stack, supports STA/AP
network role, supports multiple network working modes, supports SmartConfig, serial port transparent transmission,
power-on transparent transmission and other functions , after a simple configuration, the network access function can be
realized very conveniently, minimizing the developer's work and project development time.
