Here is a detailed description of these cables:

Length: Each cable is 20 centimeters (200mm) long, providing a convenient length for connecting components on a breadboard or other electronic projects.

Connector Type: The cables feature Dupont connectors on both ends, specifically male connectors. These connectors are commonly used in electronic prototyping and are compatible with standard 2.54mm pitch headers.

Wire Gauge: The wires are likely to be made of flexible and stranded conductors, allowing for easy bending and positioning. The specific gauge will depend on the product, but it's often designed to handle low to moderate current loads common in electronic circuits.

Color Coding: Dupont cables often come in a variety of colors, each representing a different signal or purpose. Color coding helps in organizing and identifying connections in complex electronic projects.

Quantity: The set includes a total of 40 cables, providing a generous quantity for a variety of prototyping needs. Having multiple cables in different colors enhances organization and simplifies circuit tracing.

Versatility: These jumper cables are versatile and can be used for connecting various electronic components, such as microcontrollers, sensors, LEDs, and other modules on a breadboard or prototype board.

Durability: The cables are typically designed to be durable and long-lasting, with good insulation to prevent short circuits and ensure reliable connections.

Compatibility: The male Dupont connectors on both ends make these cables compatible with a wide range of female Dupont connectors, commonly found on breadboards, development boards, and other electronic components.
