1 Human Machine Interface Platform J 0977M N01 (Preliminary) Deqing Jiahe Electronic Technology Co., Ltd. TEL: ext. 803 FAX: ext. 801 sales@jiahe electronic.com Version V1.0 1

2 1. Description The J 0977M N01 is an embedded Human Machine Interface (HMI) platform with high cost performance, it uses NUC977 as CPU. The J 0977M N01 pre installs the fully functional Linux operation System and driver software, which construct a universal embedded platform that can be directly used by users. The users can use the Eclipse and Qt integrated development environment that are provided by JHE to develop and compile application programs; these programs can be directly run on J 0977M N01. JHE provides all complete low level drivers and rich application examples to all interfaces, the users can easily and quickly develop a variety of industrial control products basing on example programs. 2. Feature 1. Powerful hardware: The NUC977 is general purpose 32 bit microcontroller embedding an outstanding CPU core ARM926EJ S with 64MB DDR2, runs up to 300MHz.It can meet the needs of a variety of large scale application programs. The J 0977M N01 supports colorful LCD; the resolution includes 320x240, 640x480, 800x480, 800x600, 1024x768, this provides more flexible choice when the users develop products UART ports: The J 0977M N01 includes 4 UART ports; it can meet the application of most existing industrial control products. It helps the users to speed up the development process and reduce the cost. 3. Wide variety of interfaces: 1 1 x RGMII; 2 2 x USB2.0 HS host or 1 USB2.0 HS host and 1 OTG; 3 1 x SPI; 4 5 x GPIO; 5 1 x Micro SD; 6 1 x PWM; 7 1 x 34 pin LCD connector with touch signal. 4. Support booting from USB, NAND and SPI FLASH. 5. Compact size: L x D: 120mm x 80mm, this is a typical compact size board with ARM9 core; it obligates a variety of general interface and mounting holes, so it can be easily assembled into different boxes to structure different products. 6. Lower application threshold: The J 0977M N01 has pre installed Linux 3.10 and Qt4.8.6 OS and standard API. So the users can use its fully functions to structure own products, even if the users do not understand the technology details of mainboard. Both Qt and open source Eclipse IDE are the mainstream development tool now, and anyone can easily grasp how to use it. As long as the users grasp the basic C/C++ programming tool (including multithread design), and know what are own needs, they will be able to finish smoothly the development of application system. It is not necessary to know the expertise of Linux OS when the users use the J 0977M N01.So it has lower application threshold and meet a variety of requirements. JHE can also customize it according to the needs of users. Version V1.0 2
