SparkFun 配件 This is a small 12mm round speaker that operates around the audible 2kHz range. You can use these speakers to create simple music or user interfaces. This is not a true piezoelectric speaker but behaves similarly. Instead of a piezoelectric crystal t

SparkFun 配件 For a long time we've had small 7-segment displays and *huge *7-segment displays but now we finally have something in between. These 20mm 4-digit 7-segment displays are big enough to see from a distance but not so big that you'd have trouble finding

SparkFun 配件 This is a simple knob that connects to the small and medium sized linear slide potentiometers. Each knob uses friction to secure itself to fit onto the slide pot. Once attached this small knob provides you with an easier to use potentiometer for you

SparkFun 配件 Polarized connectors and headers for your perf board/PCB projects. Use these connectors for power connections or any sensor/general connection to prevent users from connecting the peripheral incorrectly or reversed.This is for a pack of 20 individual

SparkFun 配件 Now for all of your coin cell battery surface mount needs the 20mm SMD Coin Cell Holder. This holder fits our 20mm Lithium Ion coin cell battery and holds the battery in place with friction. The metal housing connects to the positive (+) side of the

SparkFun 配件 This is a high quality AC to DC 'wall wart' which produces a regulated output of 12VDC at up to 600mA. These are switch mode power supplies which means the output is regulated to 12V (no more 14V outputs!) and the capable output current is much high

SparkFun 配件 These are high quality Single Pole - Double Throw (SPDT) sealed relays. Use them to switch high voltage and/or high current devices.This relay's coil is rated up to 12V with a minimum switching voltage of 5V. The contacts are rated up to 5A (@250VA
