NuMaker-IIoT-NUC980G2D USER MANUAL
1 OVERVIEW
The NuMaker-IIoT-NUC980G2D is an evaluation board based on Arm ARM926EJ-S microprocessor
NUC980DK71YC which has rich peripherals to help users to design-in their products or application
systems easily. The NuMaker-IIoT-NUC980G2D consists of two parts, a NuTFT Kit Board and a
NuMaker-IIoT-NUC980G2 board.
The NuTFT Kit Board is a daughter board that extends the NuMaker development boards. The NuTFT
Kit Board requires NuMaker development board as mother board to create a GUI development platform.
It is designed for LCD display or GUI evaluation, prototype development and validation.
The NuTFT Kit Board is equipped with one SPI flash, one LCD panel with touch function, one five
direction joystick and two push buttons. NuTFT Kit Board pin arrangement is compatible with Arduino
UNO. The driver IC of the LCD panel is ILI9341, for more detailed information about the LCD panel,
please refer to the ILI9341 datasheet.
The NuMaker-IIoT-NUC980G2 uses NUC980DK71YC microprocessor which runs up to 300 MHz with
built-in 128 MB DDR2 memory, 16 KB I-cache, 16 KB D-cache and MMU, 16 KB embedded SRAM and
16.5 KB IBR (Internal Boot ROM) for system booting from USB, SPI NAND Flash and SD/EMMC. All
functions of the NUC980DK71YC are placed on the board, including peripheral interfaces such as
memory(SPI NAND Flash, eMMC, SD), UART, Audio controller (NAU88C22YG), 10/100 Mbps Ethernet
MAC controller, high speed USB (device, HOST), JTAG, CAN and EBI. Furthermore, the board provides
Arduino Uno compatible interface for expansion. You can use it to develop and verify applications to
emulate the real behavior.

3.3.2 Pin Function Description
There is few different between NuMaker pin define and Arduino UNO pin define. The pin define of NU7
of Arduino is same as D11, D12, D13 (SPI function) and there is 1 set of SPI. The pin define of NU7 of
NuMaker is another SPI function and there are 2 sets of SPI. If user wants to operate the NuTFT Kit
Board on Arduino UNO, because it share one SPI, it recommends that control Flash and panel by
switching the SPI Flash –SS0(D10) and LCM_SPI_SS.
