The Ai-Thinker Ra-02 LoRa wireless module offers long-range, low-power wireless communication for IoT applications. Based on the Semtech SX1278 transceiver, this compact SMD module utilizes advanced LoRa™ spread spectrum technology for stable data transmission up to 10 km line-of-sight. It features high receiver sensitivity, robust anti-interference performance, and supports multiple modulation modes for flexible deployment in a variety of environments. The module includes a convenient IPEX connector for antenna integration and communicates with microcontrollers via a half-duplex SPI interface.
Features:
- LoRa™ spread spectrum modulation technology for extended range.
- Frequency range: 410–525 MHz (typically used at 433/470 MHz).
- High receiver sensitivity down to -141 dBm.
- Constant RF output power: +18 dBm ±1 dBm.
- Supports FSK, GFSK, MSK, GMSK, LoRa™, and OOK modulation.
- Half-duplex SPI interface.
- Programmable bit rates up to 300 kbps.
- Small footprint: 17 x 16 x 3.2 mm SMD package.
- IPEX antenna connector for reliable RF performance.
- Robust anti-interference and air wake-up capability.
- Operating voltage: 2.5V–3.7V (typical 3.3V).
- Low power consumption and wide operating temperature (-30°C to +85°C).
