M5Stack Module CC1101 855-925MHz

The M5Stack CC1101 module (855-925 MHz) is a powerful wireless communication module for the sub-1-GHz range. It is based on the energy-efficient CC1101 radio transceiver and utilizes the E07-900M10S module design. The frequency range of this module is between 855 and 925 MHz, enabling reliable data transmission in the license-free ISM band. The module supports various modulation techniques such as 2-FSK, 4-FSK, GFSK, MSK, ASK, and OOK for versatile radio communication. With its optimized design, it ensures stable wireless data transmission while maintaining low power consumption. The module uses an SPI interface to connect to microcontrollers or M5Stack core controllers, allowing for easy integration. Integrated DIP switches allow flexible configuration of the pins, enabling the module to adapt to different hardware setups. Additionally, multiple of these modules can be stacked together to expand functionality. A high-performance antenna can be connected via the external SMA connector to maximize the radio range. The CC1101 module is ideal for wireless control applications in areas such as industrial automation, smart home systems, automated lighting, and robotics.
