Figure 2-1 isNuTiny-SDK-N76E885 for the N76E885 series, the left portion is called NuTiny-EVB-N76E885and the right portion is Debug Adaptor called Nu-Link-Me.NuTiny-EVB-N76E885 is similar to other development boards. User can use it to develop andverify applications to emulate the real behavior. The on-board chip covers N76E885 seriesfeatures. The NuTiny-EVB-N76E885 can be a real system controller to design user’s targetsystems.Nu-Link-Me is a Debug Adaptor. The Nu-Link-Me Debug Adaptor connects your PC's USB port tothe user’s target system (via Serial Wired Debug Port) and allows user to program and debugembedded programs on the target hardware. To use Nu-Link-Me Debug adaptor with Keil, pleaserefer to “Nuvoton Nu-Link debug adapter user manual” in detail. This document will be stored inthe local hard disk when user installs each driver. Nu-Link-Me also supports virtual COM portfunction. User can use Nu-Link-Me as a USB to UART virtual COM port, which connects to on-board N76E885AT28 UART0.ICE ControllerExtended ConnectorExtended ConnectorReset Key(SW1)Power LEDICE ControllerUSB Connector（ICEJ1)GNDVCCGPIO LEDFigure 2-1 NuTiny-SDK-N76E885 (PCB Board)Virtual COM Port Switch Description2.1The switch in Nu-Link-Me, SW3, determines that the virtual COM port function is enabled ordisabled. When user turns on all of the positions of switch, the virtual COM port function will beenabled. By using virtual COM port function, user can access the USB device in the same way asit would access a standard COM port to N76E885AT28 UART0. To use this function, user needsto install “VCOM Driver” at first. User can get “VCOM Driver” from NuMicroDVDwww.nuvoton.com\NuMicroDVD in folder “Software Utilities”.NuTiny-SDK-N76E885 Power Setting and Connector2.22.2.1 Power Setting J1: USB port in Nu-Link-Me JPR1: VCC33 or VCC5 Voltage connector in NuTiny-EVB-N76E885
