1g [Feature]： Low power consumption, high cost performance [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
