【LR20-T1 Development Kit Features】The package includes STM32F103C8T6 development boards * 2,LR20 modules * 2，antennas * 2,data cables * 2. If you do not have an MCU, we recommend purchasing this T1 kit. The kit is complete and no additional accessories are required. In addition, the DX-LR20 has multiple certifications and is equipped with an RF shielding cover, providing strong anti-interference capability, ESD protection, and excellent EMC performance.
【SEMTECH LLCC68 Chip】The DX-LR20 series adopts the SEMTECH LLCC68 chip solution and integrates a newly developed generation of LoRa spread spectrum technology. Compared with SX1278/SX1276 solutions, it offers stronger performance, longer transmission distance, faster speed, and lower power consumption. It supports wake-on-radio, carrier sensing, communication encryption keys, and adjustable packet length settings.
【8KM Transmission Distance】The DX-LR20 transmission distance can reach up to 8 km (in open environment). It supports 433–532 MHz frequency band communication with 22 dBm output power. Programmable with SPI interface; firmware development must be completed by the user. 32 MHz crystal frequency, TTL level output, compatible with 3.3V–5V IO port voltage.
【Comprehensive Information】We provide complete technical support, including technical documentation, sample programs, module package drawings, reference design schematics, and development/testing tools. To help you quickly verify module functions and accelerate product development, we strongly recommend purchasing the development kit with your first order. You can access the user guide and full product information through the product guide and documentation links below.
