Overview
CC1101 433 MHz Radio Module with Spiral Antenna Transmitter and Receiver 10 mW SPI Interface 1.8 to 3.6 V Blue Board for Arduino

Compact radio module with CC1101 chip ensures bidirectional wireless communication between microcontrollers, sensors, and other electronic circuits. It operates in the licence-free band of 433 MHz, which is commonly used for remote controls, wireless sensors, and smart home applications. Each module can receive and transmit data, so a pair of modules is sufficient for basic connection between two devices. The blue board has a soldered spiral antenna made of copper wire, meaning the module does not require any additional antenna and takes up minimal space. It is suitable for hobbyists, students, and developers building projects with Arduino boards and other microcontrollers.

The control board is managed via the SPI bus, which is also used to program the operating frequency and output power. All pins are available on a 2 x 4 pin header, which can be easily connected with jumper wires or plugged into a breadboard. The operating frequency can be set in the range of 387 to 464 MHz. The module supports 2-FSK, GFSK, and MSK modulation and a data rate from 1.2 kb/s to 500 kb/s. Separate FIFO buffers of 64 bytes for receiving and transmitting, along with hardware CRC control, contribute to reliable transmission. It also features RSSI signal strength measurement, carrier detection, and WOR mode for waking up by radio, allowing the module to conserve energy while idle. A fast frequency synthesiser also supports frequency hopping.

  • Package Contents – 1 CC1101 433 MHz radio module with soldered spiral antenna

Connect the power supply to the 3.3 V output of the control board; direct connection to 5 V would not benefit the module. Do not bend or shorten the spiral antenna, as its shape and length are designed for the 433 MHz band. The range of the connection is affected by the surrounding environment, with walls, metal objects, and trees particularly attenuating the signal.

The CC1101 radio module with spiral antenna represents an economical solution for wireless sensors, lighting control, security devices, or remote data collection. The firmly soldered antenna saves space, allowing the module to fit easily into a small enclosure. An output of up to 10 mW and selectable transmission speed allow for connection settings tailored to specific projects. With a power supply of 1.8 to 3.6 V, the module can also be powered from batteries. It is an accessible option for anyone wanting to quickly test wireless data transmission in the 433 MHz band.
