A multifunctional lora expansion board

Abstract

The invention discloses a multifunctional LoRa expansion board, comprising a LoRa SPI wireless module, the LoRa SPI wireless module is respectively connected with a Raspberry Pi interface, an ART-PI P1 interface module, an ART-Pi P2 interface module and an Adruino interface module, Raspberry Pi interface\ART‑PI P1 interface module and ART‑Pi P2 interface module are connected to LoRa gateway SX1302SPI module at the same time, Raspberry Pi interface\ART‑PI P1 interface module is connected to LoRaWAN serial interface module, ART‑Pi P2 interface module Connect with 4G module. The above technical solutions make the designed LoRa expansion board integrate multiple functions, which can be conveniently and efficiently used for LoRa product prototype development, LoRa product testing, LoRa development and learning, etc. The LoRa expansion board designed using this implementation method can support both LoRa modules with multiple function types, multiple packages, and multiple frequency bands, support multiple mainstream open source hardware interfaces and their mutual conversion, and have very good compatibility and scalability.

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 been widely concerned in the field of IoT applications due to its low power consumption, long transmission distance, and simple and convenient installation. The most basic LoRa communication system usually consists of 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 is highly customizable and extensible. [0003] Chinese patent document CN209419612U discloses a "LoRa gateway expansion board for BeagleBone platform". The lorawan communication chip, front-end RF chip, power amplifier, RF switch, low noise amplifier, and BeagleBone Green standard interfa...
