A simple slide potentiometer can go a long way. Rated at 10KOhm and 0.1W. Comes with solder tab connections. The pot has an overall travel of 20mm and has two mounting holes on top. Dimensions: 9.5mm x 35mm

This is the new Arduino Uno R3. In addition to all the features of the previous board, the Uno now uses an ATmega16U2 instead of the 8U2 found on the Uno (or the FTDI found on previous generations). This allows for faster transfer rates...

The LilyPad Arduino 328 Main Board is an Arduino-programmed microcontroller designed to be easily integrated into e-textiles and wearable projects. It offers the same functionality you find in other Arduino boards, in a lightweight,...

A small, but very mighty power supply. This board was designed to be as small and inconspicuous as possible. The nice thing about LiPower is the ability to use rechargable Lithium Polymer batteries. These batteries are smaller, flatter,...

The MPR121QR2 is an I 2 C driven capacitive touch sensor controller, capable of managing up to twelve electrodes. The chip also has eight LED driving pins, which, when not configured to control electrodes, can be used to drive LEDs. The...

The LPR5150AL is low-power two-axis micromachined gyroscope able to measure angular rate along the pitch and roll axes. All required electronics are integrated onto a single chip with the sensor. The LPR5150AL has a full scale of ±1500...

The KTA-223 Relay Board is a USB or RS485 controlled module that can interface a PC to eight or more SPDT relays. This could be very useful for controlling real world devices - such as lights and sprinkler systems - and reading sensors...

This is a thermal printer like you would find on a cash register or adding machine. It will print simple strings passed to it via TTL serial, bitmap images (poorly) and it even generates several different formats of barcodes! The thermal...

This non-contact infrared thermometer makes it a breeze to take quick and accurate surface temperature readings without getting too close for comfort. Laser sighting ensures that you’re pointing at the right spot: Simply pull the trigger...

This is the SparkFun MOSFET Power Control Kit, a breakout PTH soldering kit for for the RFP30N06LE N-Channel MOSFET. This kit is extremely simple to assemble with only 10 pins to solder. If you are looking for a little more control over...

This is the same Roving Networks Bluetooth module that you already know and love, but it comes firmware-configured for the HID protocol. HID, or “Human Interface Device,” is the communication protocol used for computer peripherals such...

Digital calipers are an absolute essential. Here at SparkFun we use them all the time. These premium calipers come with an extra battery and auto shut-off. Measurements can be taken in either metric or standard. The calipers are 6" in...
