The maximum theoretical speed at which a serial communication interface can send or receive data, expressed in bits per second (bps) or its multiples such as kbps, mbps, gbps, etc. This value represents the upper bound of throughput under optimal conditions and is useful for comparing performance across different serial devices and adapters.

The colour or combination of colours that a product is available in, expressed as common names such as "Black", "Silver" or comma‑separated lists like "Black, White". It indicates the visual appearance of the item for consumers.

The physical interface or port located at the first end of a cable or device, such as USB‑A, HDMI, RJ‑45, DisplayPort, Lightning, or other standard connectors. It identifies the shape, pin count and electrical characteristics that determine compatibility with cables, adapters or other components.

The physical interface or port used to connect a device to another component, such as USB, HDMI, RJ‑45, audio jacks, or fiber optic connectors. It identifies the shape, pin count, and electrical characteristics that determine compatibility with cables, adapters, and peripherals.

The number of bits used to represent each data unit in a device’s interface or communication channel. It indicates the width of the data path and affects how much information can be transferred per clock cycle. Values are typically integers such as 8, 16, 32, or 64.

Indicates whether the product comes with drivers included in the package or available for download. A value of "Yes" means that drivers are supplied, while a value of "No" indicates they are not provided and must be obtained separately.

The amount of memory allocated for a First In, First Out (FIFO) buffer, expressed in bytes. It indicates how many data units can be stored before processing or transmission occurs.

The range of temperatures in which a product can safely operate without risk of damage or performance degradation. Values are expressed in degrees Celsius (°C) and may represent a single temperature, a minimum–maximum interval, or an average operating point.

The range of relative humidity (expressed as a percentage) within which the product is designed to operate reliably. Values are given as a minimum–maximum interval such as "20 - 80 %" and indicate the acceptable environmental moisture level for optimal performance.

The number of stop bits used in a serial communication interface. Stop bits indicate how many bit periods are transmitted after each data byte to signal the end of that byte and allow the receiver to resynchronize. Common values include 1, 1.5, or 2 stop bits.

The range of temperatures in which a device can safely operate without risk of damage or performance degradation. Values are expressed in degrees Celsius (°C) and may represent a single temperature, a minimum–maximum interval, or an average operating point.
