433MHz LoRa SX1278 Long Range RF Wireless Module DRF1278F For Arduino

XL1276-D01 wirele module is SEMTECH's latest LoRaTM modulation technology wirele , the module in addition to the traditional GFSK modulation technology, but also uses the LoRa (e) spread spectrum technology, with ultra-long 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 low-power ultra-long distance transmiion, the module is suitable for any complex envment of wirele data transmiion applications, such as: Table, intelligent home control, automotive electronics, security alarm, industrial monitoring and control systems, long-range agricultural irrigation control systand other applications. The module can be easily embedded into the customer's existing product or system design, the standard 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 transmiion.
