Evaluation Boards vs Development Boards: What's the Differences?

When you purchase components from component manufacturers, you may encounter a lot of confusing terminology. Evaluating boards versus development boards can be a good example. As a result, a vast number of manufacturers produce evaluation kits, evaluation boards, and development kits. A development kit, a development board, etc., is one of the different labels given to products.

An individual component is featured on these PCBAs. Connecting to other hardware, configuring, flashing, and configuring the board are all possible via the interfaces provided by the board. In the absence of experience with these products, it can be hard to distinguish between an evaluation board and a development board. These differences will be explored in this article, as well as whether they are actually important to your development process.

What are Evaluation Boards?

Integrated circuits (ICs), microcontrollers, and other electronic components can be evaluated and tested using evaluation boards, also known as development boards and demo boards. Usually, these boards include the IC or component that interests you, along with power supply, connectors, and peripherals that interface with it. In order to prototype and experiment with integrated circuits or components, they serve as ready-to-use platforms. In addition to documentation, samples of code, and software tools, evaluation boards often include quick-start instructions for quick setup. Before moving to full-scale production, engineers use these tools to assess performance, verify specifications, and validate designs.

What are Development Boards?

Electronic systems and applications are developed, tested, and prototyped using development boards, also called development boards or evaluation boards. Onboard peripherals include sensors, actuators, and communication interfaces (USB, Ethernet, UART, etc.) in addition to microcontrollers, microprocessors, and FPGAs. Power supplies, connectors, and various onboard peripherals are also common. Embedded systems, Internet of Things (IoT) devices, robotics, and other electronic projects can be implemented with development boards used by engineers, hobbyists, and students. A ready-to-use environment is provided to assist designers in writing and debugging code, integrating external devices, and measuring performance. New products and innovations in electronics and embedded systems can be developed quicker and more efficiently with development boards that offer thorough documentation, example code, and software development tools.

Key Differences

The key differences between evaluation boards and development boards lie in their intended use and scope:

• Purpose: ICs and components are evaluated by evaluation boards, which focus on verification and testing of their performance and functionality. In contrast, development boards provide a broader platform for building complete electronic systems, prototyping, and developing software.

• Content: A typical evaluation board will come preconfigured with the particular IC or component as well as any supporting circuitry that may be needed. Microcontrollers, peripherals, and interfaces on development boards make them more versatile platforms for diverse projects.

• Focus: In evaluation boards, single components are evaluated and validated based on their performance. Integrated electronic systems are built using a development board to develop software, prototype, and integrate multiple components.
