KL-CW11 433MHz ASK/OOK RF Receiver Module w/ Antenna
The KL-CW11 is a 433.92MHz superheterodyne RF receiver module designed for short-range wireless data links. Operating at 3-5V DC, it receives ASK/OOK modulated signals for decoding by a microcontroller, making it ideal for DIY remote control and automation projects.
Features
- High-sensitivity superheterodyne receiver with -106 dBm performance for reliable signal capture.
- Fixed 433.92MHz operating frequency compatible with common 433MHz ASK transmitters.
- Low 4mA operating current enables battery-powered, energy-efficient wireless nodes.
- Simple 3-5V DC power supply compatibility for easy integration with 3.3V or 5V logic MCUs.
- Includes integrated antenna for out-of-the-box testing and deployment in control systems.

The KL-CW11 433MHz RF receiver module implements a superheterodyne architecture for enhanced selectivity and interference rejection compared to simpler super-regenerative designs. This results in more stable performance and reliable data reception in environments with other RF noise sources. The module outputs demodulated digital data via its data pin, requiring an external microcontroller (e.g., Arduino, ESP8266) or a dedicated decoder IC to interpret the transmitted codes.
With its low current draw and wide 3V to 5V operating range, the module is suited for battery-operated remote sensors, wireless switches, and telemetry endpoints. The integrated antenna provides a basic radiating element for prototyping, while the compact 30mm form factor allows for embedding into enclosures for garage door openers, security systems, and smart home actuators.
