1 Overview

1.1 Brief Introduction

E220-900MM22S is an ultra-small volume independently developed based on a

new generation of LoRaTM RF chip LLCC68 produced by Semtech, and is suitable for

868MHz, 915MHz SMD LoRaTM wireless modules, using industrial grade 32MHz crystal

oscillator.

Since it adopts the imported LLCC68 as the core of the module, compared with

the previous generation LoRaTM transceiver, the anti-interference performance

and communication distance have been further improved. Because it adopts the new

LoRaTM modulation technology, its anti-interference performance and communication distance far exceed the current

FSK and GFSK modulation products. This module is mainly aimed at smart home, wireless meter reading, scientific

research and medical treatment, as well as medium and long distance wireless communication equipment. This product

can cover the ultra-wide applicable frequency range of 850~930MHz.

Since this module is a pure RF transceiver module, it needs to use MCU driver or use a dedicated SPI debugging

tool.
