1. Overview

1.1 Brief introduction

E19-868M20S is a small-sized 868MHz LoRa
module, based on the original imported RF chip SX1276 from SEMTECH.
Due to the use of the imported SX1276 as the core of the module, with
its stable and reliable characteristics, it is favored by the majority of users.
Compared with the FSK、GFSK products, it has made great progress in
receiving current, receiving sensitivity, transmitting power, receiving rate
range and anti-interference ability. The module is aimed at smart home,
wireless meter reading, scientific research and medical, and medium and
long distance wireless communication equipment. Since RF performance
and component selection are in accordance with industrial standards, and the
product has obtained FCC, CE, RoHS and other international authoritative certification reports, users do not need to worry
about its performance. High precision 32MHz crystal is used.
Since the module is a pure RF transceiver module, you need to use the MCU driver or a dedicated SPI debug tool.
