LLCC68 Low-power LoRaFSK Mode 868MHz Wireless RF Module Replaces SX1262 SX1276

LLCC68 is a high-performance wireless RF module launched by STMicroelectronics, designed to replace Semtech SX1262/SX1276, supports **LoRa** and **FSK** dual modulation modes, and operates in **868MHz** unlicensed frequency band. Its core advantages are **ultra-low power consumption** (sleep current <1μA, transmission current 110mA@14dBm), **long-distance transmission** (up to 15 kilometers in open environment) and **high integration** (built-in PA/LNA/DC-DC converter), which can significantly simplify the design of IoT devices and reduce BOM costs.

**Compared with traditional solutions**:
- **Power consumption optimization**: LLCC68 receives only 6.5mA of current in LoRa mode, which is 30% lower than SX1276 and is suitable for battery-powered devices (such as sensors, water meters);
- **Protocol flexibility**: Supports both LoRaWAN standard protocol and private FSK protocol, compatible with more scenario requirements;
- **Anti-interference capability**: Integrated RSSI calibration and automatic gain control (AGC), reducing the bit error rate by 40% in complex environments.

**Typical application scenarios**:
1. **Smart city**: smart meter reading (water/electricity/gas meter), remote control of street lights;
2. **Industrial Internet of Things**: equipment status monitoring, production line data collection;
3. **Smart agriculture**: soil temperature and humidity monitoring, precision irrigation system;
4. **Logistics tracking**: asset positioning (cold chain, container), warehouse management;
5. **Security monitoring**: intrusion detection, fire equipment status feedback.

**Selection Recommendation**:
LLCC68 is suitable for B-side projects that are sensitive to power consumption, require long-distance transmission, and require multi-protocol compatibility. It is especially recommended to replace SX1276 for low-speed, small-data-volume IoT terminals. Its **FCC/CE certification** and **industrial-grade temperature range** (-40℃~+85℃) further ensure compliance and reliability for global deployment. Through modular design, customers can quickly implement product iterations and shorten the development cycle.

(Note: The data is a typical value, and the actual performance needs to be tested in combination with specific scenarios.)
