1. What is LoRa module SX1278?
The wireless transceiver module SX1278 utilizes the LoRa platform, designed for IoT applications. This module communicates via the SPI protocol and can be used with any microcontroller supporting SPI. To ensure proper functioning, the module must be powered with 3.3V, and its 16 pins (8 on each side) must be connected to the uP/uC via the SPI line. It's critical to use an antenna with the module to prevent permanent damage. The module is designed to work with a standard 50-Ω impedance and comes with a spring coil antenna.
2. How does LoRa SX1278 work?
The SX1278 LoRa transceiver utilizes Semtech's patented LoRa modulation technique to enable ultra-long range spread spectrum communication and high interference immunity with low current consumption. It communicates via the SPI protocol and is compatible with any microcontroller that supports SPI. The module can be effortlessly connected to an Arduino board for transmitting and receiving data. Additionally, there are YouTube tutorials available for getting started with the LoRa SX1278 module.
3. Why LoRa is used?
LoRa is a wireless platform designed for IoT applications. It utilizes a proprietary radio communication technique based on spread spectrum modulation derived from CSS technology. LoRa is well-suited for applications that require low bit rates and transmit small data chunks over long distances, which outperforms technologies like WiFi, Bluetooth, or ZigBee. The platform is well-suited for low power mode sensors and actuators. To ensure the interoperability of all LoRaWAN products and technologies, a standard protocol known as LoRaWAN is used.
