RA-01 LoRa SX1278 Wireless Module, 433MHz Wireless Serial Port UART, +20dBm for long range touch display the phototransistor has been inThe series of modules RF chip SX1278 mainly uses LoRa remote modem for ultra long distance spread Letter, strong anti interference, to minimize current consumption. With the help of SEMTECH's LoRa Lee modulation technology, SX1278 has a high sensitivity of more than 148dBm, +20dBm power output,Transmission distance, high reliability. At the same time, relative to the traditional modulation technology, LoRa modulation technology in the anti Blocking
