LAUBEI CC1101 433MHz RF Wireless Transceiver Module with SMA Antenna
Compact 433MHz CC1101 RF transceiver module for Arduino, ESP32, ESP8266, Raspberry Pi Pico,
ESPHome and Home Assistant RF projects. Ideal for wireless sensor links, 433MHz automation,
remote-control learning projects and low-power sub-1GHz data communication.
Key Benefits
- CC1101-based 433MHz RF transceiver module
- Transmits and receives, unlike basic one-way 433MHz receiver/transmitter pairs
- SPI interface for Arduino, ESP32, ESP8266, Raspberry Pi Pico and other microcontrollers
- SMA antenna connection for improved project flexibility
- Suitable for ESPHome, Home Assistant RF bridge projects and maker automation builds
- Useful for wireless sensors, remote-control projects, data links and RF experimentation
