Piezo elements come in handy when you need to detect vibration or a knock. You can use these for tap or knock sensors pretty easily by reading the voltage on the output. They can also be used for a very small audio transducer such as a...

The Teensy is an amazing development platform that allows you to get more computing power than an Arduino Uno, and in less space. The Teensy 3.1 XBee Adapter allows you to connect your Teensy with the tried and true XBee series to...

This is a breakout board for the SP3485 RS-485 transceiver IC, which will convert a UART serial stream to RS-485. The SP3485 is a half-duplex transceiver, so it can only communicate one way at a time, but it can reach transmission speeds...

This connector cable interfaces UFL RF connectors to RP-SMA antennas. Use it to attach any standard RP-SMA 2.4GHz antenna to the our WiFly Shield. Features 4" Length

The SparkFun FTDI SmartBasic is a variation on our classic FTDI Basic board which allows you to connect a second device to the hardware serial port on an Arduino Pro, Pro Mini, or other USB-less board without compromising the ability to...

Description This is an SMD 6mm square SPST button. What we really like is the little button head and good tactile feel (it ‘clicks’ really well). This button is great for user input or a good reset button on a PCB. As this is an SMD...

The Intel® Edison is an ultra small computing platform that will change the way you look at embedded electronics. Each Edison is packed with a huge amount of tech goodies into a tiny package while still providing the same robust strength...

The LSM9DS1 is a versatile, motion-sensing system-in-a-chip. It houses a 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer – nine degrees of freedom (9DOF) in a single IC! The LSM9DS1 is equipped with a digital interface,...

These LR44 button cell batteries are fairly common but it can be hard to keep them around. They fit our digital calipers, so if you use yours as much as we use ours, you may want to go ahead and pick up a spare. Features: 1.5 VDC R44...

This single disc load cell (sometimes called a strain gauge) can translate up to 50kg of pressure (force) into an electrical signal. Each load cell is able to measure the electrical resistance that changes in response to, and...

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...

This is a high quality, 30mil standard card with a low coercivity magnetic stripe . The stripe can contain up to 3 tracks of information. This card can be erased and written multiple times with a compatible writer. Dimensions:...
