Overview
The XL1276-D01 wireless module is SEMTECH's latest LoRaTM modulation technology, which uses the traditional GFSK modulation technology, but also uses the LoRa (remote) spread spectrum technology, with the most distance spread spectrum communication, high anti-interference And minimizes current consumption. Using LoRaTM mode can achieve high -148dbm high sensitivity, and with integrated +20 dBm power output, you can achieve the maximum power transmission at the lowest power, the module is suitable for any complex environment of wireless data transmission applications, such as: wireless copy Table, intelligent home control, automotive electronics, security alarm, industrial monitoring and control systems, long-range agricultural irrigation control systems and other applications. The module can be easily embedded into the customer's existing product or system design, the standard SPI interface, making communication easy and concise. Customers only in the original micro-control device to compile a simple communication protocol, you can achieve two-way communication to achieve data transmission.
