Handy for making wire harnesses or jumpering between headers on PCB's. These premium jumper wires are a little over 6" (150mm) long and come in a 'strip' of 40 (4 pieces of each of ten colors). They have 0.1" socke...

SKU: AF-450 | Brand: Adafruit

A pack of three 74HC595 shift register ICs. These chips take a serial input (SPI) of one byte and output those 8 bits onto 8 digital output pins. Chain multiple chips together by connecting the serial output of one to...

SKU: SF-COM-09590 | Brand: SparkFun

LEDs - those blinky things. A must have for power indication, pin status, opto-electronic sensors, and fun blinky displays. This is a very basic 5mm LED with a red lens. It has a typical forward voltage of 2.0V and...

SKU: SF-PRT-14492 | Brand: SparkFun

These are your run-of-the-mill ¼ Watt, +/- 5% tolerance PTH resistors. Commonly used in breadboards and other prototyping applications, these 1K ohm resistors make excellent pull-ups, pull-downs and current limiters....

SKU: DF-FIT0110 | Brand: DFRobot

This adapter allows you to connect a barrel jack connector to bare wires. One end has screw terminals and the other has a 5.5x2.1mm, center-positive male barrel jack. If you need to connect bare wires to a barrel ...

SKU: SF-COM-09190 | Brand: SparkFun

This is a standard 12mm square momentary button. What we really like is the large button head and good tactile feel (it ‘clicks’ really well). This button is great for user input on a PCB or a good, big reset button o...

SKU: SF-TOL-09161 | Brand: SparkFun

This is your basic spool of leaded solder with a 63/37 water soluble resin core. 0.031" gauge and 100 grams. This is a good spool for more advanced users that should last 6-12 months depending on how often you solder....
