Long Range (3KM) 433Mhz Spread Spectrum LoRa Wireless Module
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.
Features
● Frequency range: 433/470/868/915 MHz (137-1020 MHZ can be customized)
● Sensitivity up to -139dBm @Lora
● Maximum output power: 20dBm
● Low receiving current: 10.3mA
● Standby current
● Data transmission rate: 1.2-300 Kbps @FSK; 0.018-37.5 Kbps @ Lora,
● LoRa, FSK, GFSK and OOK modulation modes
● Built-in antenna electrostatic protection
● 127dB dynamic range RSSI
● 256 bytes FIFO and CRC frequency hopping function
● Built-in temperature sensor and low battery indicator
● Signal is not blocked
● Operating temperature range: -40 ~ +85 °C
● Long range: 3KM in an open air (LoRa modulation)
Application
● Home security (Smart Home)
● Wireless remote control
● Wireless sensor networking
● Remote meter reading
● Energy control and management
● Smart buildings (Building Automation)
● AMR (Automatic Message Recording)
Technical Parameter
Note: Please refer to the chip register setting instructions; To ensure that the PA of the module is turned on, so as to work at the maximum power, the highest bit "PaSelect" of the 0x09 register must be set to 1.
