SparkFun 配件 This is the LM317TG voltage regulator a three-terminal positive regulator with a 1.2V to 37V adjustable output voltage. This adjustable regulator provides a local regulation internal current limiting thermal shut-down control and safe area protec

SparkFun 配件 This is 50g of high quality Lead-Free Solder Paste the perfect amount to keep around for prototyping and hobby projects that require a bit of SMD soldering. Solder Paste Stenciling is the easiest and quickest way to solder some of the trickier SMD

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 LEDs - those blinky things. A must have for power indication pin status opto-electronic sensors and fun blinky displays.This is a very standard yellow LED. The lens is 3mm in diameter and it is diffused.Features:2.0-2.4VDC forward dropMax current

SparkFun 配件 This is the SMD version of PRT-07948 which is the unit we like to use as RTC backup and SRAM backup for GPS units. Holds battery in place with friction. The metal housing connects to the positive side of the battery and the PCB pad underneath is con

SparkFun 配件 An adjustable potentiometer can open up many interesting user interfaces. With this rotary potentiometer just turn the dial and the resistance changes. This potentiometer from Bourns has a " metal knurled shaft diameter PC pin terminals no detent

SparkFun 配件 The US1881 is an integrated Hall effect latched sensor. That's nice but what does it do? Holding a magnet near the sensor will cause the output pin to toggle. This makes for a robust presence sensor. A reed sensor also works nicely but can be limite

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 red lens. It has a typical forward voltage of 2.0V and a rated forward current of 20mA.

SparkFun 配件 This is a row of 40 break away headers spaced 0.1" apart with long pins on both sides. This header is especially useful when you need to connect a PCB to a solderless breadboard. Each header can be broken apart to your preference to fit custom PCBs o

SparkFun 配件 This is a 1A Adjustable SOT-223 voltage regulator capable of outputting 1.2V to 18V. The LM1117 uses the same pin-out and setup as the popular LM317 adjustable regulator contained in a handy surface mount package. Requires two external resistors to

SparkFun 配件 If you want to get some sound out of your project but have a tight space budget this is a good way to do it. This 0.5W 8Ohm speaker is only 40mm in diameter and just over 4mm thick the same kind you might find in one of those "talking greeting car

SparkFun 配件 This is a 2x40 pin right-angle PTH header. This header can be broken apart with a fair amount of force to form smaller header formations. Don't worry it's easy enough to break it where you need! Each pin has a spacing of 0.1" in between each other.D
