Description
Specifications: LoRa1278 adopts Semtech RF transceiver chip SX1278, which adopts LoRa TM Spread Spectrum modulation frequency hopping technique. The features of long distance and high sensitivity (-139 dBm) make this module perform better than FSK and GFSK module. Multi-signal won't affect each other even in crowd frequency environment; it comes with strong anti-interference performance.ParameterMinTyp MaxUnitConditionWorking conditionWorking voltage range1.83.33.7V Temperature voltage-40 85 Current consumptionRX current 10.8 mAHigh performance modeTX current 100 mA@ 20dBmSleep current <0.2 uA parameterFrequency range403433463MHZ@ 433MHZModulation rate1.2 300KbpsFSK0.018 37.5KbpsLoraTMOutput power range-1 20dBm Receiving sensitivity -123 dBm@ FSK data=1.2kbps,Fdev=10kHZ -139 dBm@ Lora BW=125KHz_SF = 12_CR=4/5Features:
