CC1101 433 MHz Wireless RF Module with SMA Connector and Short Whip Antenna

Information about this module is generated with the help of AI. The description may be incomplete, inaccurate, or subject to change.
The CC1101 is a wireless RF transceiver module designed for communication in the 433 MHz band. Based on the Texas Instruments CC1101, the module can both transmit and receive data. It is suitable for wireless sensors, remote controls, home automation, industrial control systems, and other applications requiring long range and low power consumption.

The module communicates with a microcontroller through a standard SPI interface. Both configuration settings and transmit and receive data are transferred over SPI. The programmable GDO0 and GDO2 pins can be used as interrupt or status outputs, for example to indicate that a packet has been received or that a transmission has completed.

Operating in the Sub-1 GHz frequency band, the CC1101 provides longer range and better penetration through walls and obstacles than many 2.4 GHz solutions. It supports multiple modulation formats including 2-FSK, GFSK, MSK, ASK, and OOK, making it suitable for a wide variety of wireless applications.

The included short whip antenna connects through the SMA connector and is tuned for 433 MHz operation. The module is designed for 3.3 V logic and can be connected to controllers such as ESP32, STM32, Raspberry Pi Pico, and other SPI-compatible microcontrollers. When used with 5 V systems, logic level conversion should be used unless the host board already supports 3.3 V logic.

The 433 MHz ISM band is a license-free frequency range used for low-power short-range radio communications. In Europe, the band extends from 433.05 MHz to 434.79 MHz, with a center frequency of 433.92 MHz, which is by far the most commonly used frequency for low-cost transmitters and receivers.

Legal Notice for Radio Equipment
Owning a radio transmitter is generally permitted. Transmitting may require a license or be prohibited depending on the frequency, output power, and intended use. Using a receiver to receive radio signals is generally permitted.
