FSC-WF3821 Nordic nRF7002 Small-Size Wi-Fi 6 Module TWT

FSC-WF3821 is a highly integrated 2.4 GHz and 5 GHz dual-band Wi-Fi 6 module based on Nordic nRF7002, supports Target Wake Time (TWT), very suitable for wireless low power applications. It provided a maximum output power of 21 dBm, supports WPA3™, WPA2™, WPA™ – Personal and Enterprise, Protected Management Frames, WMM®, WMM – Power Save, Wi-Fi Agile Multiband™, Wi-Fi Direct®. The 12mm x 15mm small-size design provides designers with more flexibility. FSC-WF3821 is a great combination of low power, high performance and small size, enables more possibility for a variaty of applications.
