Chapter 1 Introduction
1.1 Brief introduction
E49-900M20S
is a cost-effective wireless data transmission
module launched by Chengdu Ebyte. It is A pure hardware module based
on CMT2300A.
E49-900M20S Supports the maximum transmission power of
20dBm, users can set a lower output power , thus saving power
consumption.The module works in the 850MHz ~ 930MHz frequency
band, including the commonly used 868MHz and 915MHz frequency
band.
Since this module is a pure RF transceiver module, using SPI
interface, needs MCU driver.
