CC1101 433MHz Wireless Transceiver Module SMA Antenna Long Distance for Wireless Alarm Security System Use

Description: 433MHz CC1101 Wireless Transceiver Module Kit with Matched Antennas, Supports Long-Range Stable Low-Power Data Transmission for IoT, DIY Electronics and Industrial Wireless Project Development Features: 1. Superior RF Performance: Powered by genuine CC1101 radio frequency chip, it delivers high receiving sensitivity at ultra-low working power consumption with strong anti-interference capability, effectively lowers data packet loss rate, and supports up to 300m open-area transmission distance for all your project needs. 2. Sturdy FR-4 Board Build: Adopts high-grade FR-4 fiberglass printed circuit board with solid solder joints, features excellent high temperature resistance, corrosion resistance, maintains stable performance even in harsh working environments, and greatly extends the service life of the module. 3. Multiple Antenna Configurations: Comes with ABS-shell pure copper oscillator rod antennas and pure copper spring antenna, provides up to 3dBi signal gain with extremely low transmission attenuation, fits different installation space requirements, and effectively improves signal stability and transmission range. 4. Low-Loss Connector Design: Uses full copper gold-plated SMA connector, has very low contact resistance and outstanding oxidation resistance, minimizes signal loss during transmission, supports repeated plugging and unplugging without performance degradation for easy assembly and replacement. 5. Plug-and-Play Pre-Calibration: Factory pre-calibrated for 433MHz ISM license-free frequency band, no extra frequency debugging required after you receive the kit, allows you to quickly integrate the module into various development projects, and saves plenty of debugging and development time.
