USB Type &lsquoB’ Female connector. The 4 connection pins have .1" spacing allowing it to be inserted into development boards and perf boards with mild modification. 

The V-TAC Golfball LED Lamps allow simple and direct replacement of old incandescent or energy-saving candle or flame lamps with up to 85% reduction in power consumption.

O AT42QT1010 SparkFun Capacitive Touch Breakout oferece um único botão de toque capacitivo com pinos de I/O digitais fáceis de usar.

This is a 2-pin, through-hole PH series JST connector. The pins are spaced by 2mm.

The LM317L device is an adjustable, 3-terminal, positive-voltage regulator capable of supplying 100 mA over an output-voltage range of 1.25 V to 32 V.

This 12-inch (30-cm) cable has 26 AWG wires and a 3-pin female JST PH-style connector that works with Sharp analog distance sensors that have mating PH connectors. The other ends of the wire are terminated with female pins for 0.1" housing. The wire color scheme matches the Sharp distance sensor pinout: red for power, black for ground, and white for signal.

This is a common barrel-type power jack for DC wall supplies. 

This is a simple three wire cable. Great for jumping from board to board or just about anything else.

USB Type &lsquoA’ Female SMD connector. For use with any PCB that will be used with a Type A to Type A USB cable.
