1. Overview

Evaluation Boards (Dev Boards) for Embedded MCUs (Microcontroller Units) and DSPs (Digital Signal Processors) are specialized hardware platforms designed to facilitate the development, testing, and prototyping of embedded systems. These boards provide a physical environment to validate processor capabilities, peripheral integration, and software algorithms before final product deployment. They play a critical role in accelerating development cycles for applications ranging from IoT devices to industrial automation systems.

2. Major Types and Functional Classification

3. Structure and Components

Typical evaluation boards consist of:

• PCB base with processor/microcontroller soldered onboard
• Memory modules (SRAM, Flash, DDR)
• Debugging interfaces (JTAG, SWD, UART)
• Power management unit (voltage regulators, PMICs)
• Peripheral connectors (GPIO, ADC/DAC, Ethernet)
• Expansion headers for add-on modules (shields, PMODs)
• Onboard sensors/actuators (depending on application focus)
