Review on 📡 Highly Reliable Comimark 2Pcs LoRa SX1278 Wireless Power Mental Module for Arduino: Extended Range up to 5Km by Luis Harper

SX1278 radio module frequency is 433MHz and 470MHz, mainly for China, Southeast Asia, South America and Eastern Europe. This device is not suitable for use in North America. In the US, 433 MHz is almost in the middle of the 70 cm amateur radio band. By law, only a licensed radio amateur can transmit on this frequency. Anyone transmitting on this frequency without a valid amateur radio license is violating Federal Communications Commission (FCC) rules and faces a hefty fine if caught.
