Sure, your flashing, chip-tune playing t-shirt is really cool at the party… but at some point you need to turn it off. And yes, you could just pull the battery, or maybe you’ve even sewn a LilyPad slide switch in-line. Wouldn’t it be...

The SparkFun Micro OLED Breakout Board breaks out a small monochrome, blue-on-black OLED. It’s “micro”, but it still packs a punch – the OLED display is crisp, and you can fit a deceivingly large amount of graphics on there. This...

This is the newest revision and fixes issues with the last board. This breakout board pairs an SP3485 RS-485 transceiver with an FT232RL USB UART IC to convert a USB stream to RS-485. The SP3485 is a half-duplex transceiver, so it can...

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 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...
