1 OVERVIEW
The NuMaker-HMI-N9H26 is an evaluation board for GUI application development. The NuMaker-HMI-
N9H26 consists of two parts: a NuMaker-N9H26 main board and a NuDesign-TFT-LCD5 extension
board. The NuMaker-HMI-N9H26 is designed for project evaluation, prototype development and
validation with HMI (Human Machine Interface) function.
The NuMaker-HMI-N9H26 integrates touchscreen display, voice input/output, rich serial port service
and I/O interface, providing multiple external storage methods.
The NuDesign-TFT-LCD5 can be plugged into the main board via the DIN_32x2 extension connector.
The NuDesign-TFT-LCD5 includes one 5” LCD with the resolution 800x480, RGB 24 bits and embedded
4-wires resistive type touch panel.
1.1 Features
