DX-LR22 Development Kit Semtech LLCC68 LORA UART Serial Transceiver modul 868 915MHz & 2PCS Antenna 22 dBm 5KM Long Rang Compatible with Arduino DIY CE FCC (LR22-900T22D(T0)

["【Transmission Distance】 DX-LR21/22 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). It supports 433–532 MHz and 850–930 MHz frequency bands, with 22 dBm power, 32 MHz crystal frequency, TTL level output, and is compatible with 3.3–5V IO port voltage.","【Original Semtech LLCC68 Chip & UART Interface】The DX-LR21/22 series is a low-power LoRa module developed by Loongtrek, based on the original Semtech SX1262 chipset. UART serial communication, enabling transparent data transmission between devices with no firmware development required. Supported baud rates include 1200, 2400, 9600, 19200, 38400, 57600, 115200, and 128000 bps.","【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-LR21/22 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 Resources】We provide comprehensive technical support, including technical documentation, AT command sets, module packages, reference design schematics, and development/test tools.
