The CC1101 Wireless Module with SMA Connector and Long Rubber Rod Antenna is a complete, ready-to-use RF transceiver solution built around the Texas Instruments CC1101 chip, designed for wireless data transmission in the 433MHz ISM band. This version features an SMA female connector and includes a long rubber rod antenna, providing excellent range, durability, and installation flexibility for both indoor and outdoor applications.
At the heart of the module is the CC1101, a highly integrated, low-power Sub-1GHz RF transceiver. The chip operates in the 300–348 MHz, 387–464 MHz, and 779–928 MHz frequency bands, with this module configured for 433MHz operation. It supports multiple modulation formats including 2-FSK, 4-FSK, GFSK, MSK, OOK, and ASK, giving developers flexibility to balance data rate, range, and power consumption.
The SMA connector allows you to attach the included long rubber rod antenna or any other 433MHz antenna with an SMA male connector. The rubber rod antenna features a flexible, durable construction that resists bending and breaking — ideal for handheld devices, portable equipment, and applications where the antenna may be subject to physical stress. The extended length of the antenna provides improved gain and range compared to shorter stub antennas.
The module delivers programmable data rates from 1.2 to 500 kbps, with programmable output power up to +10 dBm. The receiver sensitivity reaches -116 dBm at 1.2 kbps, enabling reliable long-range communication. The module also features built-in hardware CRC, forward error correction (FEC) , and data whitening for robust data integrity.
Power efficiency is a key strength. The CC1101 has low current consumption in both transmit and receive modes, and supports multiple low-power modes including sleep and wake-on-radio. This makes it well-suited for battery-powered sensor nodes and energy-harvesting applications.
The module communicates with microcontrollers via a 4-wire SPI interface (SI, SO, SCLK, CSn), making it compatible with Arduino, ESP32, STM32, and other popular platforms. Additional pins include GDO0, GDO1, and GDO2 for interrupt and status signaling.
The module operates from 1.8V to 3.6V and is widely used in wireless sensor networks, home automation, industrial monitoring, remote keyless entry, and automatic meter reading systems.
Whether you are building a wireless sensor node, a remote control system, or a handheld wireless device, the CC1101 with SMA antenna provides a proven, reliable foundation for Sub-1GHz communication. It is suitable for individual makers, students, and businesses purchasing in bulk for product development or educational programs.
