A low-cost sub-1 GHz RF transceiver module based on the Texas Instruments CC1101 IC, designed for low-power wireless communication. Pre-configured for 433 MHz operation, it is well suited for ISM and Short Range Device (SRD) applications with a transmission range of 300–500 metres depending on environment and baud rate.

The CC1101 supports multiple modulation schemes and data rates up to 500 kbps, with built-in CRC error detection, hardware address filtering, and separate 64-byte TX/RX FIFOs. The module uses a standard 2.0 mm DIP pitch interface for easy integration into embedded projects.
