Meco 868mhz / 915mhz 100mw Sx1276 Chip Long Range 4km Rf Wireless Lora Module Lora1276

Description: LoRa1276 adopts Semtech RF transceiver chip SX1276, 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. Features: Frequency Range: 868 / 915MHz Sensitivity up to -139 dBm Maximum output power: 20dBm 10.3mA@receiver mode Sleep current <200nA Data transfer rate:@FSK,1.2-300kbps @Lora TM,0.018-37.5kbps Lora TM ,FSK,GFSK and OOK Modulation mode 1.8-3.7 V Power supply 127 dB Dynamic Range RSSI Packet engine up to 256 bytes with CRC Operating Temperature Range:-40 ~ + 85 C Built-in temperature sensor and low battery indicator Excellent blocking immunity Application: Remote control Remote meter reading Home security alarm and remote keyless entry industrial control home automation remote sensing individual data records toys control sensor network tire pressure monitoring health monitoring wireless PC peripherals tag reading and writing Package included: 1 x 868MHz or 915Mhz SX1276 chip Wireless RF Module Specifications: Product name: Wireless Transceiver Module Lora1276 Parameter Min Typ Max Unite Condition Working condition Working voltage range 1.8 3.3 3.7 V Temperature voltage -40 85 Current consumption RX current 10.8 mA High performance mode TX current 100 mA @20dBm Sleep current <0.2 uA parameter Frequency range 838 868 898 MHZ @868MHZ Modulation rate 1.2 300 Kbps FSK 0.018 37.5 Kbps LoraTM Output power range -1 20 dBm Receiving sensitivity -123 dBm @FSK data=1.2kbps,Fdev=10kHZ -139 @Lora BW=125KHz_SF = 12_CR=4/5 Schematic: Pin configuration: Pin NO.
