BDE-WF3235SFA is a 802.11a/b/g/n, 2.4GHz and 5GHz Dual-Band, IPv4 & IPv6, 256KB of RAM (or 1MB of executable flash/256KB of RAM) Low Energy MCU module based on CC3235S(or CC3235SF) SoC. The module offers a unique combination of lower power, integration of all external components including Dual-band PCB Trace Antenna at a very affordable cost.
Created for IoT, the BDE-WF3235SFA module is a wireless module that integrates two physically separated on-chip MCUs, a CM4 application processor and a network processor.
BDE-WF3235SFA introduces new capabilities that further simplify the connectivity of things to the Internet. The main features of BDE-WF3235SFA include:
• 802.11 a/b/g/n: 2.4 GHz and 5 GHz support
• 2.4 GHz Coexistence with Bluetooth® low
energy radio
• Integrated Dual-band PCB Trace Antenna or UFL connector for external antenna
• More concurrent secure sockets, up to 16
• Unique device identifier with ability to
generate certificate signing request (CSR)
