The CC1101 433MHz Wireless RF Transceiver Module is an original Texas Instruments CC1101 device designed for long-range, low-power wireless communication. An improved version of the CC1100, this module operates in the ISM (Industrial, Scientific, and Medical) and SRD (Short Range Device) frequency bands from 387–464MHz. Ideal for IoT projects, remote controls, smart home devices, and wireless sensor networks, the CC1101 offers stable transmission, low noise, and extended range in compact form.
