The 114990078 application field and working principle is a type of Evaluation Boards - Expansion Boards, Daughter Cards. This type of board is designed to provide additional functionality to an embedded system. It is used in many applications, such as medical, industrial, military, and consumer applications.

The use of these boards is manifold. For example, medical applications can benefit from the additional ports and peripheral that a daughter board can provide. This additional interface can be used to connect peripherals like pressure sensors, accelerometers, and vision systems. In industrial applications, daughter boards can be used to add additional communication ports, for connecting to remote diagnostic or process control systems. These boards can also be used for data logging and storage.

The daughter board can also provide an additional level of security. It can provide tamper protection and authentication, enabling secure communication with both local and remote systems. This is especially important for military and critical infrastructure applications.

The daughter board usually consists of a microcontroller, memory, and one or more connection interfaces. Depending on the board, these can be wired or wireless connections. In terms of the microcontroller, it is responsible for providing the logic and functions needed to communicate with the systems internal devices. It is also used to process the data sent over the interfaces. This is often done with accompanying support from a Real-Time Operating System (RTOS).

The daughter boards typically include support for various types of communication protocols, including serial, data bus, controller area networks (CAN), and Ethernet. This enables the board to communicate with a variety of different peripherals. Additionally, these boards typically offer additional features, such as GPIOs, ADC and DACs, and timers.

In addition to the communication protocols mentioned, many of these boards also offer support for digital-signal-processing (DSP) and sometimes machine-learning algorithms. This makes them suitable for more advanced applications, such as medical imaging or automated control tasks for industrial systems.

When designing a system that includes a daughter board, it is important to consider the power requirements of the board. This is because the board will draw power from the system it is connected to. If the daughter board draws too much power, it could cause the entire system to fail. It is therefore important to consider the power requirements of the peripheral connected to the daughter board in order to ensure the system as a whole is not overloaded.

In conclusion, daughter boards are a type of Evaluation Boards - Expansion Boards. These boards are used in many applications, such as medical, industrial, military, and consumer applications, to provide additional functionality and security to an embedded system. They can also provide better performance through support for communication protocols as well as digital-signal-processing and machine-learning algorithms. However, when designing a system that includes a daughter board, power requirements must be taken into account to avoid overloading the system.
