LoRa1278-C1 : 433/490MHz SX1278 LoRa Module With SPI Front End Module And ESD Protection
- The LoRa module LoRa1278-C1 integrates Semtech RF transceiver chip SX1278, which adopts LoRa Spread Spectrum modulation frequency hopping technique. Its communication distance and receiving sensitivity are much better than the current FSK and GFSK modulation. Multi-signal won't affect each other even in crowd frequency environment. It comes with strong anti-interference performance. The antenna switch is integrated and controlled by the chip. Because of the compact size and output power of 100mw, it can be widely used in wireless meter reading, remote industrial control and other industries.
- LoRa1278-C1 strictly uses lead-free process for production and testing, and meets RoHS and Reach standards.
