You’ve always wanted to output analog voltages from a microcontroller, the MCP4725 is the DAC that will let you do it! The MCP4725 is an I 2 C controlled Digital-to-Analog converter (DAC). A DAC allows you to send analog signal, such as...

This is a breakout for the SOIC version of the 74HC595 shift register IC. Clock in data and latch it to free up IO pins on your micro. All pins from the IC are broken out to standard 0.1" spaced headers. The Serial in and out pins are on...

The ScrewShield extends all pins of the Arduino out to 3.5mm pitch screw terminals. It also has a lot of the utility provided by Arduino Protoshield , including: a large prototyping space of both connected and unconnected 0.1" spaced...

Here at SparkFun, we refuse to leave ‘good enough’ alone. That’s why we’re adding to our line-up of Arduino-compatible microcontrollers once more! The Pro Micro is similar to the Pro Mini except with an ATmega32U4 on board. The USB...

This is a Arduino-compatible autopilot board designed by Chris Anderson and Jordi Muñoz of DIY Drones using the ATMega328. This revision uses the ATmega2560 in place of the ATmega1280. ArduPilot Mega is a fully programmable autopilot...

This new revision includes a JST cable and also fixes the TX/RX swap from the last revision. Now you can use an FTDI correctly. We are also including a 16-pin header instead of a 40-pin header (only 16 pins are necessary). This kit is a...

Pogo pins make life so much easier when you are trying to program without having to solder a single thing, and when you attach them to an In-system programming (ISP) adapter they become instantly better, this simple kit allows you to do...

The Quadstepper motor driver board allows you to control up to 4 bipolar stepper motors simultaneously using logic level IO pins. Each motor driver has an output drive capacity of 35V and 1Amps. The board is capable of driving motors in...

This is the same product as the Joystick Shield Kit. The difference is this version comes in fancy clamshell packaging meant for our distributors that need it. Regular customers are welcome to order, but we want to limit the amount of...

This is a breakout board for Freescale’s MMA7361L three-axis analog MEMS accelerometer. The sensor requires a very low amount of power and has a g-select input which switches the accelerometer between ±1.5g and ±6g measurement ranges....

This is a SparkFun exclusive! These are 155mm long jumpers with female connectors on both ends. Use these to jumper from any male header on any board, to any other male header. Combine these with our male to male jumpers to create a male...

This is a SparkFun exclusive! These are 155mm long jumpers terminated as male to female. Use these to jumper from any male or female header on any board. Multiple jumpers can be installed next to one another on a 0.1" header. Comes as 1...
