WiFi - BDE-WF3235SA(U) (WiFi Dual-Band MCU Module Based on CC3235S)
  • BDE-WF3235SA(U) (WiFi Dual-Band MCU Module Based on CC3235S)


    The BDE-WF3235 module, is a 802.11abgn, IPv4 & IPv6 Low Energy module based on CC3235SF SoC.

    The module offers a unique combination of lower power, integration of all external components including dual band chip antenna at a very affordable cost.

    Created for IoT , the BDE-WF3235 module is a wireless module that integrates two physically separated on-chip MCUs, application processor and network processor.

    The BDE-WF3235 module is supported by easy to work with software to lower the threshold of using Wi-Fi technology or speeding up design time significantly.

    The combination of affordable cost, lowest power and ease of use makes it an ideal product for the mass market, including the makers community.
