Whether your project needs positional accuracy, high-speed movement estimations, high altitude measurements, fast update rates, or just plain ease of use, the SIM33EAU GPS Module has you covered.

Parallax’s SIM33EAU GPS Module embeds the capable SIM33EAU GPS device in a project-friendly board. Ultra compact, the SIM33EAU device has a built-in low-noise amplifier and patch antenna so there is no need for an extra antenna on the board.

The SIM33EAU GPS device gives your project the ability to read its position on the earth—given a clear view of the sky—using global navigation satellite systems such as GPS, GLONASS, Galileo or QZSS. Its default settings provide all the capabilities you would expect from a GPS receiver: location fix, speed, heading, altitude measurements, and atomic date and time. Advanced users can re-configure these settings for specific needs.

Parallax’s module makes the SIM33EAU device easily accessible to students, hobbyists, and developers. An onboard voltage regulator and buffer circuitry provide signal conditioning for use with 3.3 V or 5 V microcontrollers. Power and satellite fix LEDs let you know when your GPS module is ready and receiving data. A supercapacitor preserves almanac data for more than two hours if power is disconnected. The breadboard-friendly 7-pin header and mounting holes make for quick, solder-free integration into a project.

Great wind spinners, you can't go wrong
Size: 8 Inch
5 stars is not enough for these. OMG I found my new supplier for the wind spinners. I have gone through four other suppliers and they did not turn out well, for various reasons. But these I love for a couple of reasons. First I love that they have the paper on them for removing the plastic, holy cow was that easy! Second I love how they turn out for the ones I already made. They sublimate beautifully and the colors really pop. Thanks so much, and I'm going to order more right now! I hope you don't change them. I do recommend these folks, they are awesome.

High quality
Size: 8 Inch
got these to make some spinners for our football team and found them to be terrific. The image transfer was true to color and the size was perfect. We are going to make a few as gifts for our friends and thought the pressing of the tines out to create the spinner was quite simple. Will definitely be ordering more.
