SparkFun 配件 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 blue lens. It has a typical forward voltage of 3.4V and a rated forward current of 30mA.Fea

SparkFun 配件 A solid state relay (SSR) allows you to control high-curent AC loads from lower voltage DC control circuitry. Solid state relays have several advantages over mechanical relays. One such advantage is that they can be switched by a much lower voltage a

SparkFun 配件 This is a 16 character by 2 line display that runs at 3.3V. Utilizes the common ST7066/HD44780 parallel interface (datasheet). Interface code is widely available for many different controllers and systems. You will need 11 general I/O pins to interf

SparkFun 配件 USB Type 'Mini-B' Female SMD connector. This is a 5-pin Mini-B surface mount connector commonly found in MP3 players media/disk readers USB hubs pretty much anything small and USB.Documents: Datasheet

SparkFun 配件 These headers are made to work with the Arduino Main Board Arduino Pro and the Arduino Mega. They are the perfect height for clearing the USB-B connector and great for stacking multiple shields. This kit includes 4 headers (2 8-pin and 2 6-pin) en

SparkFun 配件 Copper tape has countless applications in electronics from creating low-profile traces for electrical components to RF-shielding and antenna-making. Copper tape is even used to join things together using solder like the stained glass on Tiffany lamp

SparkFun 配件 This is a stainless steel Type-K Thermocouple probe. A thermocouple works by taking two wires made of dissimilar metals connecting them at the two ends and making a temperature gradient between one end and the other (a 'hot' end and a 'cold' one).

SparkFun 配件 High quality switching 'wall wart' AC to DC 9V 650mA wall power supply manufactured specifically for Spark Fun Electronics. These are switch mode power supplies which mean the output is regulated to 9V (no more 14V outputs!) and the capable output cu

SparkFun 配件 Ribbon cable is really helpful in situations where you need to make a lot of connections without a big mess of wires. Nothing makes a project look more finished than a nice clean wiring harness.This is a 15ft. length of 10-wire ribbon cable. Check th

SparkFun 配件 Your basic 7-segment LED. Common anode. Two decimal points but only the one on the right is wired. Digit height is 0.6". Overall height is 1"Documents:Datasheet Arduino Library (Thanks Derek!)

SparkFun 配件 An adjustable potentiometer can open up many interesting user interfaces. Turn the pot and the resistance changes. Connect VCC to an outer pin GND to the other and the center pin will have a voltage that varies from 0 to VCC depending on the rotati

SparkFun 配件 This is a coin cell holder for the common CR2032 type battery. The holder has a neat pop-in pop-out feature that makes changing the battery easy. The feet of the holder have a small hole that allow it to be sewn without modification.
