Adafruit Ultimate GPS Logger Shield

Adafruit's Ultimate GPS, now in Arduino shield format

Brand new and better than ever, we've replaced our Adafruit GPS shield kit with this assembled shield that comes with an Ultimate GPS module. This GPS shield works great with either UNO or Leonardo Arduinos and is designed to log data to an SD card.

Flora Brake Light Backpack

Pixel-riffic motorcycle visibility

Improve your visibility on your motorcycle by installing an LED pixel display inside your backpack! This weather-resistant project uses a Flora and accelerometer to auto-detect braking and uses a simple wireless module to trigger turn signal animations.

Flora Accelerometer

Wearable 3-axis motion + compass

Add motion and direction sensing to your wearable Flora project with this high precision 3-axis Accelerometer+Compass sensor. Inside are two sensors, one is a classic 3-axis accelerometer, which can tell you which direction is down towards the Earth (by measuring gravity) or how fast the board is accelerating in 3D space. The other is a magnetometer that can sense where the strongest magnetic force is coming from, generally used to detect magnetic north. By combining this data you can then orient yourself.

DS1307 Real Time Clock Breakout Board Kit

Real time clock mini-breakout board

by Tyler Cooper

This is a great battery-backed real time clock (RTC) that allows your microcontroller project to keep track of time even if it is reprogrammed, or if the power is lost. Perfect for datalogging, clock-building, time stamping, timers and alarms, etc. The DS1307 is the most popular RTC, and works best with 5V-based chips such as the Arduino.

Lady Ada's Bento Box

Waterproof, Crushproof Pack & Hack for Arduino

Portage for your projects! Lady Ada's Bento Box is a crush-proof, drop-proof & water-proof prototyping kit that combines the ultra-rugged Otterbox 3000 with a storage tin and half-size (400-point) breadboard . In the middle is a spot for attaching an Arduino UNO (or any other PCB that has the same shape and mounting holes). There's plenty of clearance for wires (even ones with plastic bits on the end such as our premium jumper wires or wire bundles) and parts on the breadboard, and the box is so sturdy you never have to worry about any delicate parts inside getting damaged. Toss it in your backpack, suitcase, duffel bag and you can be sure to work on it when you get to school, work or home.
