Description
Unit LoRaE220-433 is a LoRa communication unit for the 433MHz frequency band launched by M5Stack, using 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, enabling point-to-point transmission and broadcast modes through convenient serial communication. The module can switch between four different working modes via an onboard DIP switch, allowing users to send and receive data without complex configurations, meeting various communication needs. It is suitable for applications such as home security alarms, building automation, smart homes, and the automotive industry.
