1. Overview
1.1 Introduction
E49-400T20S 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.
E49-400T20S can perfectly support industrial-grade applications, and
undergoes rigorous testing at the factory to ensure its industrial reliability and
batch consistency.
The E49-400T20S supports a maximum transmission power of 20dBm.
Users can set a lower output power to save power consumption. The module works at 433MHz, 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.
