10pcs 100mW 915MHz sx1276 chip Wireless RF Module LoRa1276

10pcs spring antennas

(If you need  868MHz, just leave message)

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.
