This product is EOL. Description LoRaWAN built using the RHF76-052 with optional Antennas. RHF76-052 is designed by Ai-Thinker, it is a LoRaWAN ™ UART modem & compatible device, supports LoRaWAN communication. It's based on the RHF76-052 module and an embedded LoRaWAN stack. You can use M5 core as a host MCU to control this this modem with simple AT command or UART. Since LoRa defines the lower physical layer, the upper networking layers were lacking. LoRaWAN was developed to define the upper layers of the network. LoRaWAN is a media access control (MAC) layer protocol but acts mainly as a network layer protocol for managing communication between LPWAN gateways and end-node devices as a routing protocol, maintained by the LoRa Alliance. you can upgrade your work with a LoRa / LoRaWAN radio, so it can communicate over very long distances and extremely low power consuming. By default, the UART configuration: "9600, 8, n, 1"(8 bits data, no parity, 1 stop bit) Notice: The 5 holes which are under the silk screen "LoRaWAN" are designed for upgrading the firmware of LoRaWAN module.
