The TL431A is a three-terminal adjustable regulator with a guaranteed thermal stability over applicable temperature ranges.

The LM317L device is an adjustable, 3-terminal, positive-voltage regulator capable of supplying 100 mA over an output-voltage range of 1.25 V to 32 V.

This is a SMD 4 pin right angle male header.

This is a SMD 6 pin right angle female header. 

These headers are made to work with the Arduino Uno R3, Leonardo and new Arduino boards going forward.

The LiPower board is based on the incredibly versatile TPS61200 boost converter.

The NCP1402 is a 3.3V DC-DC converter. 

This is a common barrel-type power jack for DC wall supplies. 

This LilyPad Coin Cell Battery Holder has a small slide switch installed on the board, in-line with the power so you can shut off your project and save batteries. 

This board was designed to give the user a low profile button without any sharp edges.

Blink any color you need! Use the Tri-Color LED board as a simple indicator, or by pulsing the red, green, and blue channels, you can create any color. 

This is a simple pack of five White LilyPad LEDs that are still attached to one another.

This is a simple pack of five Red LilyPad LEDs that are still attached to one another.

Detecting temperature changes has never been easier. The MCP9700 is a small thermistor type temperature sensor. 

This is a simple to use Light Sensor that outputs an analog value from 0 to 5V.

This is the newest revision of the FTDI Basic. There is a SMD 6-pin header on the bottom, which makes it smaller and more compact. Functionality has remained the same.
