Product Overview
The Raspberry Pi 40-Pin GPIO Extension Cable Kit is specially designed for Raspberry Pi enthusiasts and developers who need a convenient, reliable way to route all GPIO signals to external devices. This kit offers three selectable tail connector styles to suit different project needs:

1. Tinned Solder Pin with Insulator Caps

   • Each wire end features a 5 mm pre-tinned bare pin ready for soldering or inserting into screw-type terminals.

   • Comes with removable insulator cap for each pin to prevent accidental shorts when not connected.

2. Female DuPont Connector Version

   • Wire ends terminate in standard 2.54 mm female DuPont housings, allowing plug-in connection to male pin headers.

   • Includes two 20-pin (2×10) male DuPont pin headers so you can convert female connectors to male if needed.

   • Perfect for prototyping on breadboards or modules requiring female-header connections.

3. Male DuPont Connector Version

   • Wire ends terminate in 2.54 mm male DuPont pins for direct plug-in to female sockets or breadboards.

   • Each pin includes an insulator cap to protect the tip when not in use and to avoid shorts.

Key Features

• Full 40-Pin Breakout: Every single GPIO pin on the Raspberry Pi is available, giving you complete access to power, ground, and signal lines.

• Color-Coded and Labeled: Ten distinct colors (e.g., Red = 5V, Orange = 3.3V, Black = GND, Green = GPIO, plus Purple, Brown, Gray, Yellow, White, Blue for various I²C/SPI/UART/PWM) help prevent wiring mistakes.

• Wire Spec: 30/50cm length, AWG 22 tinned copper stranded wire. It’s flexible enough for breadboard work, yet robust for repeated bending.

• Clear Pin Markings: Each cable is silk-screened near the GPIO end with white text (e.g., “3V3”, “GND”, “SDA#2”, “SCLK#11”, etc.), so you can instantly identify each pin’s number and function.

• Safety and Durability: Both tinned and DuPont endings employ high-quality insulation. Caps protect unused pins, and connectors are snug-fit to avoid accidental disconnection.

• Plug-and-Play Ready: No need for end-user stripping or soldering (apart from solder-style variant); cables come pre-assembled, so you can get straight to prototyping.
