NUMAKER-HMI-N9H20 USER MANUAL
Maker Nu-mbed NUC472 User Manual
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.
1.1 Features

One Micro-SD/TF card slot served either as a SD memory card for data storage or SDIO
(Wi-Fi) device
One DB9 RS-232 port with UART_0 used ICL-232E transceiver chip can be served for
function debug and system development
JTAG interface provided for software development
Microphone input and Earphone/Speaker output with 24-bit stereo audio codec
(NAU88C22) for I2S interfaces
Six sets of user-configurable push button keys
SPI Flash and RS-232 interface expansion port
USB_0 that can be used as Device
System power could be supplied by DC-5V adaptor or USB VBUS
1.1.2 NuDesign-TFT-LCD4.3 Extension Board Features
4.3” resolution 480x272 4-wire resistive touch panel for 24-bits RGB888 interface.
DIN_32x2 extension connector
1.1.3 NuDesign-SPI2UART(B) Extension Board Features
Two DB9 RS-232 ports with UART used ICL-232E transceiver chip can be served for
system development.
5x2 extension connector
