10km Long Range Wireless Rf Transmitter Receiver Module 433mhz Sx1278 Lora Iot Module
[IC]：SX1278
[Frequency]：410~510MHz
[Power]：30dBm
[Distance]：10.0km
[Interface]：SPI
[Weight]：4.8±0.1g
[Introduction]：E19-433M30S is based on original imported RFIC SX1278 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.
