1. Overview
1.1 Introduction
E49-400T20D is an ultra-high cost-effective wireless module
developed by Chengdu Ebyte. There are 4 operating modes. Each
transmission mode has its own characteristics and can be applied
to various application scenarios. E49-400T20D perfectly supports
industrial-grade applications, and undergoes rigorous testing at
factory to ensure its industrial reliability and batch consistency.
E49-400T20D 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.
