Features:
The XL4432-SMD wireless module is designed by our company using Silicon Labs' Si4432 B1 chip. It is a complete compact low-power wireless transceiver module. The SI4432 is a Silicon Labs EZRadioPRO series ISM band wireless chip introduced by Silicon in 2009. It is a highly integrated wireless ISM band transceiver chip that operates in the 240-960 MHZ frequency range and has a very high receiving sensitivity (-121 dBm). And the large output power can reach +20DBm which to some extent satisfies the difficult development of RF signal amplification. Under the condition of high power setting the open communication distance can reach up to kilometer. Known as the ''king through the wall''. The module integrates all RF related functions and devices. Users do not need to know the relevant knowledge of the radio and can easily develop stable and reliable wireless related products using this module.
The XL4432-SMD is carefully designed and manufactured based on the original information of Silicon Corporation and is a feature of the chimeric SI4432.
The module components all use Murata's high-frequency inductors and capacitors and the crystal's high-precision specifications of 10ppm ensure that the wireless characteristics of the module are fully reflected.
The professional OEM processing factory in Shenzhen uses high-precision placement machine to process environmentally-friendly lead-free solder. All modules are tested by professional equipment and the consistency and stability of the modules are fully guaranteed.
SPI interface small size stamp hole interface for easy embedded design fully extend the distance so that your equipment performance to a higher level.
