Introduction to UGFC: Standard Specification for Module Computers (Core Boards)

1. Concept

UGFC stands for Unified Gold Finger Core Board, which refers to a standardized small computer module specification defined by Wuhan Wanxiang Aoke Electronics Co., Ltd. This specification is designed for embedded, low-power, and general-purpose applications, utilizing a 204Pin gold finger connector based on an ARM architecture MPU platform, primarily targeting data acquisition, edge data processing, interface communication, and human-machine interaction in various industrial scenarios.

2. Main Features and Significance

Standardized Interfaces and Dimensions: The UGFC standard defines a specification for the size, connector type, electrical characteristics, and functional interfaces of computer modules.

Improved Compatibility and Interchangeability: The unified size and interface function definitions allow different manufacturers or different computer modules from the same manufacturer to be interchangeable on the same base board (also known as carrier board or bottom board). This greatly enhances compatibility and interchangeability among core boards. Users can choose different processor brands and core boards with varying performance without worrying about compatibility issues with the base or carrier board.

Reduced Development Costs: For developers, different sizes and interfaces of core boards mean that they need to adapt and develop for different hardware, which increases development and time costs. With a unified standard, developers can use standardized packaging and definitions, lowering the development threshold and costs.

Reduced Maintenance Costs: Under a unified standard, the maintenance and upgrades of core boards become simpler and more convenient. Users do not need to prepare different testing tools and adaptation materials for core boards of different sizes and interfaces, reducing maintenance and time costs.

3. Module Types and Sizes

The UGFC standard defines one module size of 67.6mm x 45mm. The module PCB has 204 gold fingers, which can connect to a 204-pin 0.6mm pitch gold finger connector socket.

4. Technical Specifications and Interfaces

The UGFC series core boards support various display interfaces, 2 Gigabit Ethernet interfaces, 6 user serial ports, USB, CAN, SATA, PCIe, and necessary auxiliary interfaces, supporting scalability while meeting the demand for smaller sizes.

5. Compatible Platforms

The UGFC series core boards are compatible with the Rockchip RK3562, RK3568, RK3576, RK3588, Allwinner T507, and Xinchih D9 series processors.

The compatible design allows for functionality testing and verification using the same evaluation board.
