Ai-Thinker LoRa Ra-02 433MHz Long Range Spread Spectrum RF Wireless Module

The Ai-Thinker LoRa Series Ra-02 Spread Spectrum Wireless Module is a long-range, low-power RF communication module based on the Semtech SX1278 / SX1276 LoRa transceiver technology. Designed for IoT, smart agriculture, telemetry, remote monitoring, and wireless sensor applications, the Ra-02 module offers robust communication across long distances with excellent interference immunity and minimal power consumption. Operating in the 433MHz ISM band, this module supports LoRa spread spectrum modulation, allowing extended communication range and high link reliability. With an SPI interface and small form factor, the Ra-02 integrates easily with microcontrollers like Arduino, ESP32, STM32, and Raspberry Pi, making it ideal for embedded wireless systems.Features:Based on Semtech LoRa RF transceiver (SX1278 / SX1276)Spread spectrum LoRa modulation for long-range communication433MHz ISM frequency band operationHigh receiver sensitivity for robust signal receptionLow power consumption for battery-operated systemsSupports multiple modulation modes: LoRa, FSK, GFSK, OOKSPI interface for easy microcontroller integrationCompact SMD module suitable for embedded designsExcellent anti-interference and stable RF performanceSpecifications:Model: Ra-02 (Ai-Thinker LoRa Series)Chipset: SX1278 / SX1276 (LoRa RF Transceiver)Frequency Band: 410–525 MHz (optimized for 433MHz)Modulation Modes: LoRa / FSK / GFSK / OOKOutput Power (Max): Up to +20 dBmReceiver Sensitivity: Up to -148 dBm (LoRa mode)Data Rate: 0.3 kbps – 37.5 kbps (LoRa mode)Interface: SPI (3.3V logic)Operating Voltage: 1.8V – 3.7V (typical 3.3V)Transmit Current: ~120 mA (max at high power)Receive Current: ~10–12 mASleep Mode Current: < 1 µAAntenna Connector: On-board pad (IPEX/U.FL optional)Operating Temperature: -40°C to +85°CModule Type: SMD Wireless RF TransceiverExplore AI Thinker Modules featuring ESP8266 and ESP32 chipsets with WiFi, Bluetooth, and RF capabilities, perfect for IoT development, wireless communication, automation systems, and embedded engineering projects.Package Includes:1 × Ai-Thinker LoRa Ra-02 433MHz Long Range Spread Spectrum RF Wireless Module
