433 MHz CC1101 wireless RF transceiver module with SPI and spring 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 compact, high performance wireless RF transceiver module designed for communication in the 433 MHz ISM band. Based on the Texas Instruments CC1101 chip, it provides reliable two way wireless communication with high receiver sensitivity, low power consumption and programmable output power.

The module communicates through an SPI interface and is compatible with Arduino, ESP8266, ESP32, STM32, Raspberry Pi and many other microcontrollers. Support for multiple modulation formats including 2-FSK, GFSK, MSK and ASK OOK makes it suitable for a wide range of wireless applications.

A 433 MHz spring antenna is preinstalled, allowing communication distances of up to approximately 1000 meters depending on the antenna, configuration and surrounding environment. High receiver sensitivity helps maintain stable communication over long distances.

The compact module features a 1.27 mm pin pitch. Please note that it cannot be plugged directly into a standard 2.54 mm breadboard without an adapter or wired connections.

Typical applications include home automation, wireless sensors, remote control systems, telemetry, IoT devices, alarm systems and industrial control equipment.

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.
