433MHz LoRa SX1278 Module DRF1278F
Home > Product > Wireless Module > LoRa Modem Module
DRF1278F is a type of low cost RF front-end transceiver module based on SX1278 from Semtech Corporation. It keeps the advantages of RFIC SX1278 but simplifies the circuit design. The high sensitivity (-139dBm) in LoRa modulation and 20dBm high power output make the module suitable for low range and low data rate applications.
Features:
* (G)FSK/4(G)FSK/LoRa Modulation
* 433MHz transceiver
* 20dBm output power
* -139dBm sensitivity
* Standard SPI interface
* 127dB dynamic Range RSSI
* Automatic RF sense and CAD monitor
* Data Rate: <300 kbps
* Standby current: <1uA
*Supply voltage: 1.8~3.6V

Application:
* Remote Control * Remote AMR  * Home Automation * Personal data logger * Wireless sensor network * Remote Keyless entry * Wireless PC peripherals
DRF1278F module consists of RFIC SX1278, thin SMD crystal and antenna matching circuit. The antenna port is well matched to standard 50 Ohm impedance. Users don't need to spend time in RF circuit design and choose suitable antennas for different applications. DRF1278F operates at 1.8~3.6V with extra low standby current which makes it suitable for battery powered-up applications. Because DRF1278F is purely hardware module and it adopts ±10ppm crystal which the resolution of it places a important role in calculating spreading factor, bandwidth, etc. Users need to read the datasheet of SX1278 carefully in order to use the module in the best performance. DORJI also provides sample codes based on microcontroller and Arduino platform. The customers who buy the modules can contact the sales of DORJI for modifiable copies.
