1 OVERVIEW
The NuMaker-HMI-N9H20 is an evaluation board for GUI application development. The NuMaker-HMI-
N9H20 consists of three parts: a NuMaker-N9H20 main board, a NuDesign-TFT-LCD4.3 extension
board and a NuDesign-SPI2UART(B) extension board. The NuMaker-HMI-N9H20 is designed for
project evaluation, prototype development and validation with HMI (Human Machine Interface) function.
The NuMaker-HMI-N9H20 integrates touchscreen display, voice input/output, rich serial port service
and I/O interface, providing multiple external storage methods.
The NuDesign-TFT-LCD4.3 can be plugged into the main board via the DIN_32x2 extension connector.
The NuDesign-TFT-LCD4.3 includes one 4.3
” LCD with the resolution 480x272, RGB 24 bits and
embedded 4-wires resistive type touch panel.
The NuDesign-SPI2UART(B) can be plugged into the main board via the 5x2 extension connector. The
NuDesign-SPI2UART includes two DB9 RS-232 ports with used ICL-232E transceiver chip.
