G400S Description
The G400S SoM is powerful, low-cost, surface-mount System on Modules (SoM) running Microsoft's .NET Micro Framework. The .NET Micro Framework enables the SoM to be programmed from Microsoft Visual Studio using a USB or serial cable. Programming in a modern managed language, such as C# or Visual Basic, allows developers to accomplish more work in less time by taking advantage of the extensive built-in libraries for networking, file systems, graphical interfaces, and more.

- Operating Temperature
The operating temperature is the range of ambient temperature within which a power supply, or any other electrical equipment, operate in. This ranges from a minimum operating temperature, to a peak or maximum operating temperature, outside which, the power supply may fail.

- Size / Dimension
In electronic components, the parameter "Size / Dimension" refers to the physical dimensions of the component, such as its length, width, and height. These dimensions are crucial for determining how the component will fit into a circuit or system, as well as for ensuring compatibility with other components and the overall design requirements. The size of a component can also impact its performance characteristics, thermal properties, and overall functionality within a given application. Engineers and designers must carefully consider the size and dimensions of electronic components to ensure proper integration and functionality within their designs.
1.90 x 1.30 48.3mmx33.1mm - Part Status
Parts can have many statuses as they progress through the configuration, analysis, review, and approval stages.
Active - Moisture Sensitivity Level (MSL)
Moisture Sensitivity Level (MSL) is a standardized rating that indicates the susceptibility of electronic components, particularly semiconductors, to moisture-induced damage during storage and the soldering process, defining the allowable exposure time to ambient conditions before they require special handling or baking to prevent failures
6 (Time on Label) - Speed
In electronic components, "Speed" typically refers to the rate at which data can be processed or transferred within the component. It is a measure of how quickly the component can perform its functions, such as executing instructions or transmitting signals. Speed is often specified in terms of frequency, such as clock speed in processors or data transfer rate in memory modules. Higher speed components can perform tasks more quickly, leading to improved overall performance in electronic devices. It is an important parameter to consider when designing or selecting electronic components for specific applications.
400MHz - RAM Size
RAM size refers to the amount of random access memory (RAM) available in an electronic component, such as a computer or smartphone. RAM is a type of volatile memory that stores data and instructions that are actively being used by the device's processor. The RAM size is typically measured in gigabytes (GB) and determines how much data the device can store and access quickly for processing. A larger RAM size allows for smoother multitasking, faster loading times, and better overall performance of the electronic component. It is an important factor to consider when choosing a device, especially for tasks that require a lot of memory, such as gaming, video editing, or running multiple applications simultaneously.
32KB Internal 128MB External - Core Processor
The term "Core Processor" typically refers to the central processing unit (CPU) of a computer or electronic device. It is the primary component responsible for executing instructions, performing calculations, and managing data within the system. The core processor is often considered the brain of the device, as it controls the overall operation and functionality. It is crucial for determining the speed and performance capabilities of the device, as well as its ability to handle various tasks and applications efficiently. In modern devices, core processors can have multiple cores, allowing for parallel processing and improved multitasking capabilities.
ARM926EJ-S - Module/Board Type
Module/Board Type refers to the specific type or form factor of an electronic component, module, or circuit board. It describes the physical layout, size, shape, and configuration of the component or board, which determines how it can be mounted, connected, and integrated into a larger system. Common module/board types include single-board computers, microcontroller boards, expansion modules, and various types of interface boards. Understanding the module/board type is crucial for selecting compatible components, designing circuits, and ensuring proper functionality and connectivity within an electronic system.
MPU Core - Flash Size
Flash size refers to the amount of non-volatile memory available in an electronic component, typically measured in bytes, kilobytes, megabytes, or gigabytes. It determines how much data or instructions can be stored permanently even when power is removed. Flash memory is commonly used in devices such as microcontrollers, smartphones, USB drives, and solid-state drives to store firmware, applications, and user data. The flash size can significantly impact the functionality and performance of a device, influencing how many applications can be installed or how much data can be retained.
4MB External - RoHS Status
RoHS means “Restriction of Certain Hazardous Substances” in the “Hazardous Substances Directive” in electrical and electronic equipment.
