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.
