Description
The LoRaE220-433 Unit is a 433MHz LoRa communication module released by M5Stack, utilizing the LLCC68 chip solution. Compared to the traditional SX1278 solution, the LLCC68 offers advantages such as longer transmission distance, faster speed, and lower power consumption. This unit supports features like over-the-air wake-up, carrier sensing, and communication keys. It achieves point-to-point and broadcast transmission modes through convenient serial communication. The module includes an onboard DIP switch that allows users to switch between four different operating modes, enabling easy data transmission and reception without complex configurations. It is suitable for various applications, including home security alarms, building automation, smart homes, and the automotive industry.
