The RHT03 (also known by DHT-22) is a low cost humidity and temperature sensor with a single wire digital interface. The sensor is calibrated and doesn’t require extra components so you can get right to measuring relative humidity and...

These DC powered heating pads are perfect for near-body heating applications. They get warm to the touch but not too hot as long as you provide the appropriate voltage. Simply apply 5VDC to the wire leads and within minutes, the pad will...

Servos are awesome for robotics projects but they can be difficult to mount the way you want. Luckily, our brilliant Ministry of Machinery has spun up these plastic servo mounts.

This is a basic 8 character by 2 line display with black text on green background. The screen utilizes the extremely common HD44780 parallel interface chipset. Interface code is freely available. You will need ~11 general I/O pins to...

The MPR121QR2 IC is a great way to build simple capacitive touch interfaces, and now it’s even easier to incorporate into your Arduino projects with the touch shield. The touch shield has 9 capacitive touch pads, with headers for the...

This charger accurately balances and charges Lithium Polymer, LiFe (A123), NiCd and NiMH batteries. It will handle LiPo/LiFe up to 6S and NiMH/NiCd up to 15S and shows individual cell voltage during charge with realtime updates...

The TSL235R light-to-frequency converter outputs a square wave (50% duty cycle) with frequency directly proportional to light intensity (irradiance). The device has been temperature compensated for the ultraviolet-to-visible light range...

This is a handy little Bluetooth USB mini-adapter. This adapter supports Bluetooth v2.0 class 1 and has a maximum distance of up to 100m. The adapter also includes an indicator LED. Great for laptops and if you’re on the go! This device...

It's blue! It's thin (0.8mm)! It's the Arduino Pro Mini! SparkFun's minimal design approach to Arduino. This is a 5V Arduino running the 16MHz bootloader. Arduino Pro Mini does not come with connectors populated so that you can solder in...

Has your “Check Engine Light” turned on in your car and you don’t know what could possibly be wrong? We get it, it’s a stressful situation that no one wants to be subjected to, and that’s why we created the SparkFun Car Diagnostics Kit!...

The ProtoSnap series is a new way to prototype your project without a breadboard. Everything is wired together on a single board, which makes it easy to explore the possibilities of the components before snapping them apart and building...

This is a time saving kit of jumper wires - cut, stripped, and pre-bent for your prototyping pleasure. Included with this kit are 14 various lengths of 22AWG wire - 2, 5, 7, 10, 12, 15, 17, 20, 22, 25, 50, 75, 100, and 125mm - 10 pieces...
