Evaluation Boards - Expansion Boards, Daughter Cards

1. Overview

Evaluation Boards (EVBs), Expansion Boards, and Daughter Cards are essential hardware tools for embedded system development, prototyping, and testing. These platforms enable engineers to assess processor capabilities, interface peripherals, and validate designs before mass production. Their modular architecture supports rapid innovation in IoT, automotive, industrial automation, and consumer electronics sectors.

2. Main Types and Functional Classification

Type	Functional Features	Application Examples
Microcontroller EVBs	ARM/FPGA SoC integration, onboard sensors, debug interfaces	IoT edge devices, smart sensors
Expansion Boards	Standard interfaces (PCIe, USB-C), protocol converters	Industrial gateways, communication modules
Daughter Cards	Specialized functionality modules (ADC/DAC, RF transceivers)	Medical imaging equipment, test instruments
Programmer Kits	Flash programming, JTAG/SWD debugging, voltage monitoring	Automotive ECUs, aerospace controllers

3. Structure and Components
