ATmega328P powers this GPS Cookie

Designed by Richard Haberkern, the open source GPS Cookie is built around Atmel’s popular ATmega328P microcontroller (MCU). As Haberkern notes, the Cookie’s compact form factor (available in two form factors, or shapes) makes it easy to carry, experiment with and expand.

“Take it with you, throw it in a bag or redesign the whole thing to create your own unique version of this GPS data logger. The unique open access design let’s you write code, make design changes and test your applications as you go. Think of the GPS Cookie or Sandwich as a prototyping platform and fully functional product in one great design,” Haberkern wrote in a recent Kickstarter post.

“Just insert two AAA batteries and any micro SD card to start recording and location data. The on board LEDs will tell you when the GPS Cookie is receiving satellite data and recording your route history. After your car ride, bike trip, walk or any other journey is over, just pull out the SD card, upload it to Google Earth and you are ready to view everywhere you or the GPS Cookie or Sandwich has been.”
