The XL4432-SMD is a high-performance 433M wireless transceiver module with multiple modulation modes. It works in the 433.92M international common ISM band, with a maximum modulation rate of 256KBPS
The module size is 17*16.5mm, and the single-row pin interface with 1.27mm spacing is designed with an external antenna. At 1.2K speed in the open area, the test distance of transmitting and receiving 10 bytes of data can reach about 1200 meters
Operating frequency 433.05-434.79M conforms to international general ISM regulations; high sensitivity -121dBm@1.2kBPs; maximum output power 20dBm
The module integrates all radio-frequency-related functions and devices. Users can easily develop wireless-related products with stable and reliable performance without knowing the relevant knowledge of radio.
