1.1 Brief Introduction

E49-400M20S is a cost-effective wireless data transmission module launched by Chengdu
Ebyte. It is a pure hardware module based on CMT2300A.
E49-400M20S supports a maximum transmit power of 20dBm, and users can set a lower
output power to save power consumption. The module works in the 410MHz ~ 510MHz
frequency band, covering the commonly used 433MHz and 470MHz frequency bands.Since
this module is a pure RF transceiver module, it uses an SPI interface and requires an MCU
driver.
