NuMaker-HMI-N9H31-A2

NuMaker HMI N9H Series

Nuvoton offers the HMI platform which is embedded with Nuvoton N9H MPU. The N9H31 series with ARM926EJ-S core can operate at up to 300 MHz. It integrated TFT-LCD display controller, 2D graphics accelerator, and JPEG codec, supporting resolution up to 1024x768 pixels in parallel port, and the color depth up to 16.7 million colors ( 24-bit ) LCD screen output to deliver gorgeous display effects. It embedded up to 32 MB DDR SDRAM, along with ample hardware storage and computing space for excellent design flexibility. 

NuMaker-HMI-N9H31-A2 Overview

The NuMaker-HMI-N9H31-A2 is an evaluation board for GUI application development. The NuMaker-HMI-N9H31-A2 consists of two parts: a NuMaker-HMI-N9H31 main board and a NuMaker TFT-LCD5 extension board. The NuMaker-HMI-N9H31-A2 is designed for project evaluation, prototype development and validation with HMI (Human Machine Interface) function.

The NuMaker-HMI-N9H31 integrates touchscreen display, voice input/output, rich serial port service and I/O interface. The NuMaker-TFT-LCD5 can be plugged into the main board via the DIN_32x2 extension connector. The NuMaker-TFT-LCD5 includes one 5” LCD which the resolution is 800x480 with RGB-24bit and embedded the 4-wire capacitive type touch panel.
