Reference Design / Application Evaluation Kit

    • Evaluation Board - BD91N01NUX-EVK-001
    • The EVK premises operation by VBUS power, so this EVK does not require an external power source. The EVK has a Type-A receptacle and is provided power from a Source device connected to the Type-C receptacle of the VBUS. The Type-C features of this EVK can be evaluated by connecting a USB Type-A Captive Cable or Type-A Plug device such as a mouse or a USB memory stick.
