The RPI-1031 tilt sensor is capable of sensing a change in orientation in four different directions: forward, back, left or right. This breakout board makes it easier to incorporate the RPI-1031 in your next project by breaking the...

A simple slide potentiometer can go a long way. Rated at 10kOhm and 0.5W. Comes with solder tab connections. The taper profile for this slide can be found in the datasheet below labeled “0B”

This is a breakout board for Blackberry Trackball. The four spindles on the trackball have a tiny circular magnet the end; each of these are paired with an SMD hall effect sensor, which are used to measure up, down, left and right...

Faster, cheaper, smaller, better, right? The SN754410 Quad Half H-Bridge is just that. Capable of driving high voltage motors using TTL 5V logic levels, the SN754410 can drive 4.5V up to 36V at 1A continuous output current! Please see...

This is the new PICkit 3 from Microchip. If you want an official programmer from Microchip, this is it! The PICkit 3 allows debugging and programming of PIC and dsPIC microcontrollers using the powerful graphical user interface of the...

This new version uses an SMD 5x2 header. This is a simple to use USB AVR programmer. It is low cost, easy to use, works great with AVRDude , and is tested extensively on a Windows desktop. Based on Dick Streefland’s USBtiny and Limor...

Have you ever wanted to control the flow of a liquid using your computer or microcontroller, but didn’t know how? Well, here’s how: The 12V solenoid controlled fluid valve. Simply connect a fluid source to the ¾" threaded inlet and it...

Here is a simple, low-cost, high quality servo for all your mechatronic needs. This servo is very similar in size and specifications to the Hitec HS-55. This little guy is able to take in 6 volts and deliver 20.8 oz-in. of maximum torque...

This pan/tilt bracket consists of two brackets and all the hardware you need to attach them to make a pan/tilt mechanism using two servo motors. We recommend our small servo motors listed below. Note: Servos are not included. The...

What is a ‘laser card’ you ask? It is only the coolest thing to hit Spark Fun Electronics since the Color LCD last week! Don’t be fooled by the 0.8mW rating. This little module is powered with 3V and projects a very clear, bright, red...

This is an evaluation board for the MLX90614 IR Thermometer. The sensor is connected to an ATmega328 running at 3.3V with a STK500 (Arduino) 8MHz bootloader. Code can be loaded through the FTDI basic interface and the Arduino...

Ready to add audio to your next project? This small breakout board couples a small electret microphone with a 100x opamp to amplify the sounds of voice, door knocks, etc loud enough to be picked up by a microcontroller’s Analog to...
