1 Introduction

1.1 Brief Introduction

E19-900M20S2 is an ultra-small 915MHz SMD LoRaTM wireless
module independently developed based on the SX1276 produced by Semtech in
the United States. It uses an industrial-grade high-precision 32MHz crystal
oscillator.
Because the original imported SX1276 is the core of the module, its
stability has won unanimous praise from users, and there is no need to worry
about compatibility. Because of its advanced LoRaTM modulation technology,
its anti-jamming performance and communication distance are far beyond the
current FSK and GFSK modulation products. This module is mainly aimed at smart home, wireless meter reading,
scientific research and medical treatment, and medium and long-distance wireless communication equipment. Radio
frequency performance and component selection are in accordance with industrial standards.
Since this module is a pure radio frequency transceiver module, it needs to be driven by MCU or a dedicated SPI
debugging tool.
