LoRa Module Spi 20dBm Long Range Wireless Transceiver 433MHz Rf Module
[IC]：SX1278
[Frequency]：410-525MHz
[Power]：20dBm
[Distance]：5.0km
[Interface]：SPI
[Weight]：1.1±0.1g
[Introduction]：E19-433M20S2 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.
