1 Introduction

1.1 Brief Introduction

E220-900m22s is an small module, self-developed based on the new

generation of LoRa

TM

RF chip llcc68, produced by Semtech company. It is

suitable for 868mhz and 915MHz LoRa

TM

wireless module and uses industrial

32mhz crystal oscillator.

Compared with the previous generation of LoRa

TM

transceiver, its

anti-jamming performance and communication distance have been further
improved. Because of its new LoRa

TM

modulation technology, its anti-jamming

performance and communication distance are far superior to the current FSK
and GFSK modulation products. The module is mainly aimed at smart home,
wireless meter reading, scientific research and medical and medium and long distance wireless communication
equipment. The product can cover a wide frequency range of 850 ~ 930mhz.

Because the module is a pure RF transceiver module, it needs to use MCU driver or special SPI debugging tool.

1.2 Application
