- BDE-WF3220SFN(WiFi MCU Module Based on CC3220SF)
-
- General Description
The WF3220 module, is a 802.11b/g/n, IPv4 & IPv6 Low Energy module based on CC3220S/F SoC.
The module offers a unique combination of lower power, integration of all external components except antenna.
Created for IoT , the WF3220 module is a wireless module that integrates two physically separated on-chip MCUs, application processor and network processor.
The WF3220 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.
