Description
The CC1101 Wireless Module is a compact, low-power Sub-1GHz RF transceiver built around the Texas Instruments CC1101 chip, designed for wireless data transmission in the 433MHz ISM band. It is an ideal solution for IoT projects, wireless sensor networks, remote control systems, and any application requiring reliable, long-range communication at low power consumption.
At the heart of the module is the CC1101, a highly integrated, low-cost RF transceiver designed for low-power wireless applications. 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 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 available in a compact SMD package. It 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 an IoT gateway, the CC1101 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.
