Ra-01SC LLCC68 LoRa Wireless RF Module 410-525MHz SPI IPEX

Ra-01SC (LLCC68) LoRa Wireless RF Module 410–525MHz with SPI & IPEX

The Ai-Thinker Ra-01SC is a compact LoRa/(G)FSK wireless RF module based on the LLCC68 chipset, designed for reliable long-range communication in industrial and IoT applications. It supports an SPI interface and uses an IPEX (U.FL) antenna connector for flexible antenna selection and installation.

Ra-01SC is suitable for low-power, long-distance data links where stable performance and strong anti-interference capability are required, including telemetry, sensors, and remote control systems.

Key features

• Model: Ra-01SC (LLCC68-based LoRa RF module)
• Frequency band: 410–525MHz (ISM range depends on local regulations)
• RF output power up to +22dBm
• High receiver sensitivity (typ. < -129dBm class, application dependent)
• SPI host interface for MCU integration
• IPEX (U.FL) connector for external antennas
• Compact SMD package for production assembly
