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.

Closing it when you have a ring.
Color: Black, Color: Black
Its a nice box but the problem i have with it is the middle piece. It does not give enough room if you have a ring that sits high like a cocktail ring. And same if you have a pendant necklace in the necklace area. You have ro really force it closed and i worry that it will put pressure on the items. It would work better without that middle piece for earrings or maybe if it were half the size. Closes fine when its empty but the minute you put a ring in the ring spot that has any kind of height you have to squeeze it shut. Its a good little box that you can put in a safe. Thats why i use it. Just to put my good jewelry in it and then secure it properly in a small house safe. Also ive already had the backs of a few earring pop off when I've opened the earring flap because it all rubs together. .
