This is a blue colored 40 Pin 2.54 mmط single row pin header strip from DFRobot.
These 0.1" header strips are commonly used as low-cost Arduino connectors. The standard spacing allows use with solderless breadboards, perforated prototyping PCBs, female headers, and our premium and pre-crimped jumper wires. The single-row header strips can easily be snapped into smaller strips to fit your application.ط¢آ
These colored pin headers will help you label pin rails depending on their function.ط¢آ
We commonly use:
- Green for Digital I/O
- Blue for Analog I/O
- Red for Voltage
