2.4G SX1281 Development Kit Lora Wireless uart RF Module DX-LR42-24T12D 13dbm 3.7KM High Speed Low Power FLRC 150kb/s GFSK TTL 3.3V IoT RF Module for Arduino Raspberry Pi ESP32

DX-LR42 SX1281 Development Kit – Ready to Use, No Secondary Development Required：Powered by the Semtech SX1281 chip, this development kit delivers reliable long-range wireless communication in the global 2.4GHz ISM band, making it ideal for IoT, industrial automation, smart agriculture, robotics, and wireless data transmission applications.

• 【3.7 km Transmission Distance】DX-LR41 is based on the SX1281 RF chip, operating in the 2.4GHz ISM band with no regional restrictions. With 13dBm output power, the communication distance can reach up to 3.7 km in open environments (e.g., using a drone). It supports multiple modulation modes including LoRa, FLRC, balancing long-range and high-speed communication needs.
• 【Original Semtech SX1281 Chip & UART Communication】The DX-LR41 series is a low-power 2.4GHz module developed by Loongtrek. It uses UART serial communication and requires no development, enabling transparent data transmission between devices. The baud rates supported are 2400、9600、19200、38400、57600、115200.
• 【AT command settings】Has multiple AT commands that can be used to set query the module's Mode, Frequency, Mac, Bandwidth, Spreading factor, Coding rate, Coding rate, etc. You can quickly start the project without writing the lora program by yourself.
• 【Application Scenarios】DX-LR41 has good anti-interference capability and stable communication performance, making it suitable for building private wireless communication systems. It supports low-latency, high-speed serial wireless communication and is applicable to various indoor and outdoor scenarios, such as from the living room to the basement, home yard, warehouse, and industrial environments.The module can be used with Arduino, Raspberry Pi, or ESP32 for applications such as remote control, data collection, and IoT development. We provide rich example codes to facilitate quick development and verification.
