2pcs/lot 868MHz | 915MHz 100mW sx1276 chip long range 4Km RF Wireless LoRa Module LoRa1276

aeProduct.getSubject()

 

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-interferenceperformance. 

 

 

Features:

  • Frequency Range: 868/915MHz (Customizable 137-1020 MHZ)
  • 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
