[price-up] 4432 SMD Wireless Transceiver R2 (433M,1KM Range)


Availability: Out of stock SKU: NWL1062 Category: Tags: , , ,


4432-SMD wireless module is used by the company using the Silicon Labs Si4432 B1 version of the chip carefully designed, it is a complete, compact, low-power wireless transceiver module. EZRadioPRO series ISM band wireless chip of Silicon Labs SI4432 by Silicon launched the company in 2009, it is a highly integrated wireless ISM band transceiver chip can work within 240-960 MHZ frequency range with high receiver sensitivity (- 121 dBm) and the maximum output power can reach + 20DBm, which to some extent to meet the RF signal amplification development difficult problem. By then the maximum power setting conditions, open communication distance up the kilometers.

Known as “King through the wall,” he said. Module integrates all RF devices and related functions, users do not need to understand the relevant knowledge of the radio, you can use this module to easily develop a stable and reliable wireless related products.


  • 4432-SMD is based on the company’s original Silicon relevant information from well-designed professional manufacturing, the most fitting of various characteristics SI4432.
  • Murata high-frequency device module used in all specifications of inductance and capacitance, the crystal of 10ppm precision specifications ensure that the wireless module features to be fully reflected.
  • From Shenzhen professional OEM factory using precision SMT lead-free solder processing, all modules have been professional equipment testing, consistency and stability of the modules are fully protected.
  • SPI interface, small size volume, convenient Stamp Interface embedded design, fully extended from your equipment performance to the next level.
