Introduction:

XL4432-SMT is a cost-effective 433M wireless transceiver module designed by wireless transceiver IC CMT2300A. It has multiple modulation modes. The module's transmit power, working frequency, modulation rate and other parameters can be configured by the microcontroller. Based on the SPI interface, it is convenient for various MCU connections. Can do a variety of wireless two-way data transmission and reception, the microcontroller through the SPI control wireless module to transmit, receive data or sleep, the wireless module receives data through the NIRQ port to notify the microcontroller to receive, the microcontroller reads the data received by the wireless module through the SPI interface.
