E19-915M20S

[IC] : SX1276

[Frequency] : 900~931MHz

[Power] : 20dBm

[Distance] : 5.0km

[Interface] : SPI

[Introduction] : E19-915M20S is based on original imported RFIC SX1276 from SEMTECH, adopts LoRa spread spectrum technology. Which means the transmitting distance is much longer than before, besides the power density is more concentrated and anti-interference performance is better.
