Unit LoRaE220-433

SKU:U170-433

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.

Operating Mode Configuration

LoRaE220-433 Operating Modes

Operating Mode (0-3) M0, M1 Description
0: Transmission Mode M0:OFF, M1:OFF Normal data packet transmission and reception mode
1: WOR Transmit Mode M0:ON, M1:OFF Send WOR data packets, this mode also supports data reception (support for over-the-air wake-up)
2: WOR Receive Mode M0:OFF, M1:ON Disable data transmission, this mode only supports WOR data packet reception
3: Configuration Mode M0:ON, M1:ON Switch to configuration mode, used for configuring module transmit power, channel, address, etc.
schematics
The "ON" in the table above stands for "0" in the datasheet;" "OFF" stands for "1" in the datasheet.
