Retired Product 433mhz Lora Sx1278 With Antenna Xl1278 Smt Spi Interface Long Range Transceiver Wireless Module In Pakistan

SX1278  wireless module is SEMTECH’s latest LoRaTM modulation technology wireless chip, the module in addition to the traditional GFSK modulation technology, but also uses the LoRa (remote) 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 transmission, the module is suitable for any complex environment of wireless data transmission applications, such as: 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.
