KKSB Case for Raspberry Pi 5 and M.2 NVMe HAT

Jargon buster

Plain-language definitions for the technical terms used above.

DIN

As a pin label, DIN stands for 'data in', the input through which a device receives serial data from a controller, as found on SPI displays, LED drivers and other serial modules. DIN can also refer to the German standards body of that name, as in a round multi-pin DIN connector or DIN-rail mounting.

DIN rail

DIN rail is a standard metal mounting rail used inside industrial electrical cabinets. When a product is DIN rail mountable, it can be clipped neatly alongside power supplies, relays and other automation hardware in a panel.

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.

M.2

M.2 is a compact edge-connector standard for plugging small modules - such as SSDs, wireless cards or microcontroller modules - into a host board without soldering. The same slot shape can carry different interfaces (for example PCIe, SATA or USB), so keying and the supported module type need to be checked.

NVMe

A high-speed storage standard commonly used by modern SSDs. NVMe support matters if you want faster storage for large AI models, video files or operating system images than a typical microSD card can provide.
