LoRa1278 : 433/490MHz LoRa Wireless Module With ESD Protection
- LoRa1278 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. This wireless module antenna switch is integrated and controlled by the chip. Its compact size is matched with an output power of 100mw. It can be widely used in wireless meter reading, remote industrial control and other industries.
- LoRa1278 comply with lead-free craft in production and testing and meets RoHS and Reach standards.
