1. Overview

1.1 Introduction

E49-900T20S is an ultra-high cost-effective wireless module launched by
Chengdu Ebyte. It has 4 operating modes. Each transmission mode has its own
characteristics and can be applied to various application scenarios. E49-900T20S
can perfectly support industrial-grade applications, and undergoes rigorous testing
at the factory to ensure its industrial reliability and batch consistency.
The E49-900T20S supports a maximum transmission power of 20dBm. Users
can set a lower output power to save power consumption. The module works at
868-915MHz, with TTL level output, and is compatible with 3.3V. The module has data encryption function. The data
transmitted by the module in the air is random. Through strict encryption and decryption algorithms, the data interception
is meaningless, the probability of interference is reduced, and the reliability and transmission efficiency are improved.
Besides, it is a low-cost wireless serial transceiver module.
