Power Supplies - External/Internal (Off-Board)

Power supplies are essential components in any electronic device, providing the necessary voltage and current to keep them running. They come in two main types: internal and external. Internal power supplies are built into the device, while external power supplies, also known as off-board power supplies, are separate units that plug into the device. External power supplies offer several advantages over internal ones, including easier replacement and greater flexibility in terms of voltage and current output. In this article, we will explore the differences between internal and external power supplies and their respective pros and cons.
