Multifunctional LoRa expansion board

Abstract

The invention discloses a multifunctional LoRa expansion board, and the expansion board comprises a LoRa SPI wireless module; the LoRa SPI wireless module is connected with a Raspberry Pi interface\ART-PI P1 interface module, an ART-Pi P2 interface module and an Adruino interface module; the Raspberry Pi interface\ART-PI P1 interface module and the ART-Pi P2 interface module are simultaneously connected with a LoRa gateway SX1302SPI module, the Raspberry Pi interface\ART-PI P1 interface module is connected with a LoRaWAN serial port interface module, the LoRa gateway SX1302SPI module is connected with a LoRa gateway SX1302SPI module, and the ART-Pi P2 interface module is connected with the 4G module. According to the technical scheme, the designed LoRa expansion board integrates multiple functions and can be conveniently and efficiently used for prototype development of LoRa products, LoRa product testing, LoRa development and learning and the like; the LoRa expansion board designed by using the implementation method can simultaneously support LoRa modules with multiple function types, multiple packages and multiple frequency bands, simultaneously support multiple mainstream open source hardware interfaces and mutual conversion thereof, and has very good compatibility and expansibility.

Description

technical field [0001] The invention relates to the field of LoRa wireless communication, in particular to a multifunctional LoRa expansion board. Background technique [0002] According to data, in recent years, LoRa wireless communication has attracted widespread attention in the field of Internet of Things applications due to its characteristics of low power consumption, long transmission distance, and simple and convenient installation. The most basic LoRa communication system usually includes three parts: base station, relay and terminal. Within the range allowed by the communication distance, single-hop or multi-hop transmission can be realized between the base station and the terminal through the relay, and the protocol has strong customization and scalability. [0003] Chinese patent document CN209419612U discloses a "LoRa gateway expansion board for BeagleBone platform". The lorawan communication chip, front-end radio frequency chip, power amplifier, radio frequen...
