Jargon buster

Plain-language definitions for the technical terms used above.

API

An API (application programming interface) is a defined set of commands or functions that lets one piece of software interact with another, such as a library, operating system, hardware driver or online service. When something offers API support, it means you can control or query it from your own code rather than only through its built-in menus or buttons.

DC

DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.

DSI

DSI stands for Display Serial Interface, a high-speed connection commonly used to send video data from a computer board to a display. It matters because DSI signals are not simple GPIO wires, so the cable, connector, and signal routing need to match the display interface.

eMMC

Embedded MultiMediaCard is built-in flash storage soldered onto a board, similar in purpose to an SD card but integrated. It matters because it holds the operating system and files without needing a separate memory card.

GPIO

General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.

HDMI

HDMI is a common digital video and audio connection used by computers, media players, and many displays. If a display kit has HDMI input, it is usually much easier to test with a single-board computer because it can act like a normal monitor.

Headers

Rows of connector contacts on a fixed pitch (commonly 2.54 mm) used to link a board to a breadboard, jumper wires, or another board. They come as male pin headers and female socket headers; when a module ships with pre-soldered headers it can be used straight away, whereas bare pads require soldering the pins yourself.

LPDDR4

A low-power type of RAM commonly used in phones and embedded computers. More LPDDR4 memory lets a board run larger programs, Linux services, or AI models more smoothly.

MIPI

MIPI is a high-speed display and camera interface often used inside phones, tablets, and embedded devices. It matters because raw MIPI displays usually need special driver hardware or software support, unlike plug-and-play HDMI screens.

MIPI-CSI

A camera interface used on many embedded computer boards to connect compact camera modules directly to the processor. It matters for vision projects because it can handle high-resolution camera data with less overhead than a USB camera.

single-board computer

A complete computer built onto one circuit board, usually including the processor, memory, ports, and connectors. This matters because accessories like heatsinks must match the board’s layout and mounting holes to fit properly.

TOPS

TOPS means trillions of operations per second, often used to describe AI accelerator performance. It helps compare whether a computing module is suited to lightweight image recognition or more demanding neural-network workloads.

USB Type-C

USB Type-C is a small, reversible USB connector used for power, data and sometimes video on many modern devices. The connector itself does not guarantee a particular speed or voltage, so check the supported USB version, data rate and whether it carries more than 5V via USB Power Delivery.
