SparkFun 配件 Coin Cell Battery Holder - 20mm (PTH)

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 This is an incredibly simple one cell 18650 Battery Holder. When someone thinks of 18650 Cells they tend to think of flashlights first which is fair since that is what they have been primarily used for. However with this battery holder you will gai

SparkFun 配件 These are very thin variable potentiometers. By pressing down on various parts of the strip the resistance linearly changes from 100Ohms to 10 000Ohms allowing the user to very accurately calculate the relative position on the strip. Can be used as
