1. Overview
1.1 Brief introduction
E19-915M20S is a small-sized 915MHz LoRa
TM
SMD wireless module,based on the original imported RF chip
SX1278 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.
