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.
