Ai Thinker LoRa Series Ra-02 Spread Spectrum Wireless Module

Ai Thinker LoRa Series Ra-02 Spread Spectrum Wireless ModuleThe Ai Thinker RA-02 LoRa Module is a high-performance long-range wireless communication module based on LoRa (Long Range) spread spectrum technology. It operates in the 433/868/915 MHz frequency bands and provides low-power, long-distance data transmission, making it ideal for IoT (Internet of Things), smart city, and industrial wireless applications.The module uses the Semtech SX1278/SX1276 chip, which integrates LoRa modulation technology to achieve long-distance communication with low power consumption. With an SPI interface, it can be easily interfaced with microcontrollers like Arduino, STM32, Raspberry Pi, and other embedded systems.The RA-02 is compact, lightweight, and designed for reliable wireless networking in harsh environments, enabling remote sensing, data acquisition, and telemetry systems.Click here to view related productsFeatures:Frequency Range: 433MHz / 868MHz / 915MHz (depending on variant)Modulation: LoRa spread spectrumChipset: Semtech SX1278 / SX1276Output Power: Up to 20dBm (depending on hardware and configuration)Sensitivity: Up to -137 dBm (LoRa mode)Communication Interface: SPIOperating Voltage: 1.8V – 3.7V (recommended 3.3V)Data Rate: 0.3 kbps – 37.5 kbpsAntenna Interface: External antenna pin (SMA/connector)Low Power Consumption: Sleep mode supported (<10 ?A)Operating Temperature: -40°C to 85°CDimensions: ~32mm × 17mm × 3mmAdvantages:Long-range communication up to 5–10 km (line of sight)Ultra-low power consumption for battery-powered IoT devicesHighly resistant to interference due to spread spectrum technologyEasy integration with Arduino, STM32, Raspberry Pi, and other MCUsCompact and durable design for industrial and outdoor environmentsApplications:IoT Networks: Smart meters, home automation, and sensor networksIndustrial IoT: Remote monitoring, equipment control, and telemetrySmart Agriculture: Wireless soil moisture, temperature, and environmental sensorsSmart Cities: Street lighting, parking management, and environmental monitoringRemote Control & Robotics: Long-distance wireless device controlWireless Data Transmission: Low-bandwidth telemetry over long distances* Product image for illustration purposes only, actual product may vary.
