4PCS DX-LR02 with 4PCS SMA Antenna LORA UART Serial Transceiver Module 868915MHz AT Conmand 22 dBm 5KM Long Rang ASR6601 Main Chip Compatible with Arduino CEFCC Certification(LR02-ANT 868 915MHz)

The DX-LR02 868/915Mhz Developer Kit is suitable for personal DIY or users who need to quickly verify communication products. The product does not require development, has built-in programs, and can communicate directly using AT commands.

• 【Reliable Product】The DX-LR02 can achieve a communication range of up to 5 km in an open, unobstructed environment when used for drone communication (actual communication distance may vary depending on the environment; please refer to actual testing), including CE, FCC, and ROSH. This makes your product safer and more reliable.
• 【UART Serial communication】DX-LR02 is a low-power lora module developed by DX-SMART. Serial communication can achieve transparent data transmission between devices. The baud rate supports 1200, 2400, 9600, 19200, 38400, 57600, 115200, 128000.
• 【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】The DX-LR02 enables long-distance serial data transmission, for example, from the living room to the basement, from the living room to the yard, on pastures, on farms, and within industrial parks. It can also be used with Andruno, Raspberry Pi, or ESP32 MCUs to develop various DIY products, such as long-distance motor control and data acquisition. We have extensive sample code to quickly verify your product.
• 【Rich Documentation Resources】We provide comprehensive technical support, including technical documentation, AT command sets, module packages, reference design schematics, and development/test tools. To help you quickly verify module functionality and accelerate product development, we strongly recommend purchasing a development kit with your initial order.
