A whole computer on a card, and the power supply is part of the board
A single-board computer runs a full operating system on one small board, and it sits between a microcontroller and a desktop: it controls a 3D printer, drives a camera, serves a web page, runs an emulator. The processor and RAM are published, and RAM is usually soldered, so the size bought is the size kept. Storage is a microSD card on most boards, with eMMC or an NVMe slot on others, and the difference decides how fast the system feels and how long it lasts. The GPIO header — its pin count and layout — decides which add-on boards fit, and a board that follows a common layout inherits a large accessory catalog. Ports are listed by type and count: video outputs, USB, Ethernet and its speed. The power requirement is the specification most often ignored: many boards need a supply of a stated voltage and current through a specific connector, and an underpowered supply causes instability rather than a clear error. Cooling — a heatsink, a fan, a case — matters under sustained load, when a hot processor slows itself. Then operating system support, which differs widely between the reference board and compatible alternatives. We compare processor, RAM, storage options, GPIO header, ports, power requirement, cooling and operating system support.

A single-board computer runs a full operating system. The two shelfs are distinct in this catalog.
It depends on the services hosted. Published RAM says what the board carries.
The published power requirement says so. An insufficient supply is a cause of faults that are hard to diagnose.
Published cooling describes what the manufacturer provides for: heatsink, fan or nothing.
Published storage options specify it. Some models accept a more durable medium.
Published operating system support prevails. Outside that list nothing is assured by the manufacturer.
Connecting components and expansion boards. Its format is published on every listing.
Published ports list the physical connectivity. They decide which adapters are needed.
Add the power supply, cooling and storage to the cost of any bare board, and compare reseller prices with official ones.
There is no table here, and the reason is in the listings. The figure published most often across these 8 products is board, given by 4 of them — short of the four in five a column needs to compare rather than to display gaps. Each product page says what its own maker published.
$170 – $275
