CC1101 Wireless RF Transceiver Module — Key benefits and features Reliable multi-band RF communication: Supports 433 / 868 / 915 MHz operation for consistent, interference-resistant data transmission across common ISM bands. Improved signal reception with SMA antenna: Supplied SMA antenna increases sensitivity and transmission range, delivering more stable links and better coverage for remote or obstructed environments. Flexible frequency expansion: Continuous frequency expansion options let you pick the best band for your application. Supported ranges: CC1100: 400–464 MHz and 800–928 MHz CC1101: 387–464 MHz and 779–928 MHz Clear function and compatibility: Acts as a wireless transceiver module compatible with systems requiring RF links in the listed bands and ranges. Easy to integrate into custom radio, telemetry, or remote-control systems. Wide operating voltage: Works across a broad supply range (8-3.6V), allowing integration with different power sources and existing electronics. Performance-oriented design: Built to provide reliable data transmission and reception in a variety of deployment scenarios when paired with appropriate antennas and system design. Why customers choose this module Solves connectivity gaps where wired links are impractical by providing dependable wireless links across multiple common frequency bands. Reduces rework and compatibility issues by offering flexible frequency options (both CC1100 and CC1101 ranges) so one module family can serve multiple regional or application requirements. Improves real-world reliability with an SMA antenna option that increases range and signal stability. Typical use scenarios Home and building automation: Wireless sensor networks and remote switches operating on 433 / 868 / 915 MHz bands for lighting, security sensors, or HVAC control. Industrial telemetry and monitoring: Remote data collection from environmental sensors, asset trackers, or machine-health monitors where reliable RF links and selectable frequency ranges are required. Remote controls and long-range links: Wireless control of gates, irrigation systems, or telemetry nodes that need stable reception and flexible frequency selection to meet regional regulations. What to check before integration Confirm regional frequency regulations for 433, 868, or 915 MHz and choose the appropriate frequency range (CC1100 or CC1101) for compliance. Match antenna type and placement to your coverage needs; the included SMA antenna improves reception but system performance depends on antenna choice and installation. Verify your power supply is compatible with the module’s stated working voltage (8-3.6V) range. This CC1101 module provides practical, multi-band RF capability with enhanced antenna performance and flexible frequency options, suitable for a wide range of wireless communication projects.
