Evaluation boards, also known as expansion boards, daughter cards, daughter boards, and evaluation modules are engineering electrical hardware used to assess the function and features of a particular system. The boards are designed to provide an interface to allow experimental data to be obtained for evaluation, thereby confirming correct performance.

Unlike typical circuit boards, evaluation boards are based on a specialized design that is created for the sole purpose of researching the features of a new product or device. Thus, they are commonly employed in research laboratories or research and development departments of businesses and manufacturing facilities.

Evaluation boards can be used for numerous types of evaluation, including feature testing, device testing, system programming, data logging and operations testing. Some may be constructed in such a way that they will run consistently under varying conditions, allowing their performance to be checked against predetermined parameters. Depending on the content of the board, they may also be used to program devices or circuits or to measure circuit operation.

Typical evaluation boards consist of a printed circuit board (PCB) that holds all of the components required to test the device or system in question. Many types of components, including capacitors, resistors, power transistors and digital logic integrated circuits (ICs) may be placed on the board, depending on the application. Some evaluation boards are also equipped with external connectors for connecting additional testing equipment.

The major components and standardized connectors are connected to an application specific integrated circuit (ASIC) or system on a chip (SoC). This allows the evaluation board to interact with various input and output devices, such as IR sensors, display screens or optical input devices.

Evaluation boards are often equipped with a variety of on-board configuration switches to adjust the device\'s settings. This gives the user more control over the testing procedure, allowing for changes in test parameters during the course of testing. In most cases, the testing process is completely automated, with the board controlling the device or system under test.

The majority of evaluation boards are sold by companies specializing in the manufacture of testing hardware. Depending on the complexity of the design, various types of technological support may be provided for the evaluation hardware, such as software and firmware updates, technical support and customer training.

Conclusion

In conclusion, evaluation boards are highly specialized devices used in the testing of electronic systems and devices. By providing an interface between hardware and software, they are able to facilitate testing and performance evaluation of system features and product features. Throughout all stages of production and design, evaluation boards provide insight into system requirements and performance capabilities, making them invaluable tools for modern development.
