M5Stack CC1101 Module (855-925MHz)

The M5Stack CC1101 Module offers low-power Sub-1 GHz wireless communication with SPI, DIP-switch pin routing and multi-modulation support — ideal for smart home, automation and robotics projects.

The M5Stack Module CC1101 is a high-performance wireless communication module based on the E07-900M10S solution, featuring a built-in CC1101 low-power Sub-1 GHz RF transceiver. It supports an operating frequency range of 855–925 MHz and works with multiple modulation types, including 2-FSK, 4-FSK, GFSK, MSK, ASK and OOK, enabling stable wireless data transmission with low power usage.

The module communicates over SPI and includes onboard DIP switches for flexible pin configuration, making it easy to stack or combine with other modules for expanded functionality. It’s well suited for wireless control applications such as industrial automation, smart home systems, automated lighting and robotics.
