The TLC5940 is a 16 channel PWM unit with 12 bit duty cycle control (0-4095), 6 bit current limit control (0-63), and a daisy chainable serial interface. This breakout board is a good way to take full advantage of this useful IC. All 16...

If you want to get some sound out of your project but have a tight space budget, this is a good way to do it. This 0.25W, 8Ohm speaker is only 40mm in diameter and just over 4mm thick, the same kind you might find in one of those...

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...

This sealed digital temperature probe lets you precisely measure temperatures in wet environments with a simple 1-Wire interface. The DS18B20 provides 9 to 12-bit (configurable) temperature readings over a 1-Wire interface, so that only...

This is the SparkFun XBee Explorer Dongle unit for the Digi XBee module line. With the XBee Explorer Dongle you can plug the unit directly into your USB port and have it act as a gateway between your computer and the XBee. No cables...

XBee radios are an awesome way to add wireless capability to your Arduino project and now it’s even easier with the SparkFun XBee Shield. The shield form-factor mates directly with any dev board that has an Arduino standard footprint and...

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...
