Quantity:

Long Range (3KM) 433Mhz Spread Spectrum LoRa Wireless Module with SPI Interface


M-SX1278S2 wireless module is designed with Semtech’s LoRa spread spectrum chip SX1278, which is an upgraded version of our S1 module (DL-RTS1278). The module adopts spread spectrum modulation technology to solve the communication distance problem that cannot be achieved by traditional FSK modulation communication technology. 

It is configured with different spreading factors to minimize the impact of co-frequency interference and has super anti-interference. This LoRa module is designed with an output power of 100mw and is very compact. It can be widely used in industries such as wireless meter reading and remote industrial control.
