Ra-01SC LLCC68 LoRa RF Module 410-525MHz – 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. 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 — telemetry, sensors, remote control systems. The +22 dBm RF output power delivers strong link budget for kilometer-scale deployments. High receiver sensitivity (typical < -129 dBm class) supports robust signal recovery at distance.
Key Features
- Model: Ra-01SC (LLCC68-based LoRa RF module).
- Frequency band: 410-525 MHz (ISM range depends on local regulations).
- RF output power up to +22 dBm.
- High receiver sensitivity (typ. < -129 dBm class, application dependent).
- SPI host interface for MCU integration.
- IPEX (U.FL) connector for external antennas.
- Compact SMD package for production assembly.
Typical Applications
- Smart agriculture — soil moisture sensors, livestock tracking over kilometers.
- Smart city — parking, lighting, waste monitoring.
- Industrial telemetry — remote tank levels, vibration sensors, equipment monitoring.
- Environmental monitoring — weather stations, water quality, air quality.
- Asset tracking — long-range location reporting for vehicles, containers.

FAQ — Ra-01SC LLCC68 LoRa Module
Q: LLCC68 vs SX1278 — what's the difference?
A: LLCC68 is the cost-optimized variant of the SX126x family — supports LoRa modulation at typical end-device data rates (smaller spreading factor range vs full SX1262 / SX1268). For most IoT end-device applications, LLCC68 delivers the same range / link budget as SX126x at lower cost. For gateway / concentrator designs, use SX1301 / SX1302 multi-channel chipsets.
Q: 410-525 MHz — which exact ISM band for my region?
A: 433 MHz (EU / Asia) and 470 MHz (China) sit within this range. Confirm your local ISM band regulations before deployment. The module's wide frequency range means firmware can target the appropriate sub-band for your region.
Q: Can I run it from a 3.3V MCU?
A: Yes — typical SPI interface compatible with standard 3.3V MCU GPIO (STM32, ESP32, Arduino Pro Mini 3.3V). Verify exact supply spec (typically 1.8-3.7V VBAT) and add 3.3V LDO if your power rail differs.
Q: Bulk pricing for OEM production?
A: Yes — email contact@lys-sz.com with your quantity for tier pricing on Ra-01SC modules.
