Chapter 1 Overview
1.1 Introduction
Based on PANCHIP’s RF chip PAN3031, the E29-T series products are a new generation of wireless serial port
module (UART) independently developed by Chengdu Ebyte Electronics Co., Ltd. It’s with a variety of transmission
methods, working in the frequency band 410.125
~
493.125MHz (default 433.125MHz), and using industrial-grade
high-precision 32MHz crystal oscillator.
The E29-T series adopts a new generation of ChirpIoT™ spread spectrum technology, supports half-duplex wireless
communication, has the characteristics of high anti-interference and high sensitivity; It also has air wake-up, wireless
configuration, automatic relay, communication key, AT Command, IAP upgrade and other functions; This series of
modules is mainly for application in smart home, industry, scientific research, medical and short-distance wireless
communication equipment. It supports packet length setting, and customized development service is also available.

1.2 Features
Support AT command, more convenient for use.
Support IAP upgrade, more convenient to update firmware;
ChirpIoT™-based modulation method brings longer communication distance and stronger anti-interference ability;
Support automatic relay networking, multi-level relay is suitable for ultra-long-distance communication, and
multiple networks run simultaneously in the same area;
User can set the communication key by himself and the key cannot be read by others. It greatly improving the
confidentiality of user data;
