Chengdu Ebyte Electronic Technology Co., Ltd.
1 Overview
1.1 Brief Introduction
E220-400MM22S is an ultra-small volume independently developed based
on a new generation of LoRaTM RF chip LLCC68 produced by Semtech, and is
suitable for 433MHz, 470MHz 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 410~493MHz.
Since this module is a pure RF transceiver module, it needs to use MCU driver or use a dedicated SPI debugging
tool.
