If you’re looking for a simple way to add a battery to your LilyPad project, the LilyPad Coin Cell Battery Holder might do the trick. It’s a simple board which holds a 20mm coin cell battery (such as a CR2032) and gives you 4 connection...

The LilyTiny is a tiny little LilyPad board designed to add flashy functionality to your project without taking up a lot of room. Even though it’s as small as some of the LilyPad sensors, this board actually has an ATtiny microcontroller...

This is the SparkFun MiniGen Signal Generator, a small shield for the Arduino Pro Mini that is capable of generating sine, square, or triangle waves at up to 3MHz, and approximately 1Vp-p. Though the MiniGen is technically a shield it...

Power on the go? Why didn’t you ask? We’ve got plenty! These portable, rechargeable lithium-polymer battery packs are simple, compact and make for a great way to power your widgets in the field. Best of all, they’re dead simple to...

This is a 4" connector cable that interfaces U.FL RF connectors to regular SMA connectors.

This is your simple three conductor sensor cable with electrode pad leads. These cables are 24" long and feature a 3.5mm audio jack connector on one end with snap style receptacles for biomedical sensor pads. Each cable comes in a...

A solid state relay (SSR) allows you to control high-curent AC loads from lower voltage DC control circuitry. Solid state relays have several advantages over mechanical relays. One such advantage is that they can be switched by a much...

The AD8232 Single Lead Heart Rate Monitor is a cost-effective board used to measure the electrical activity of the heart. This electrical activity can be charted as an ECG or Electrocardiogram and output as an analog reading. ECGs can be...

This is the MS5803-14BA Pressure Sensor Breakout, a high resolution pressure sensor with both an I2C and SPI interface. This MEMS pressure sensor measures the absolute pressure of the fluid around it which includes air, water, and...

This is a 10 pack of Biomedical Sensor Pads, disposable electrodes that can be used to measure EEG, ECG and EMG levels. these little pads are perfect for short-term monitoring of Neurofeedback and Biofeedback purposes. They are to be...

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 yellow lens. It has a typical forward voltage of 2.0V and a rated forward...
