Chengdu Ebyte Electronic Technology Co.,Ltd.

1. Overview

1.1 Introduction

E103-W03 is an ultra-low power serial port to Wi-Fi module, small size SMD
package, PCB antenna, working in the 2.4~2.484GHz frequency band. The module
can use the serial port to send and receive data, which reduces the threshold for
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 immediately. It supports the function of
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, it can be very convenient to realize
the network access function, and minimize the developer's work and project development time.
