Parallax SIM33EAU GPS Module

Parallax SIM33EAU GPS Module embeds the ultra-compact SIM33EAU GPS device in a project-friendly board. This GPS module enables any project to read the position on Earth using global navigation systems such as GPS, GLONASS, Galileo, or QZSS. Parallax SIM33EAU GPS Module provides all the capabilities of a GPS receiver including location fix, speed, heading, altitude measurements, and atomic date and time. This GPS module features an onboard voltage regulator and buffer circuitry that provide signal conditioning for use with 3.3V or 5V microcontrollers. Power and satellite fix LEDs indicate when the GPS module is ready and receiving data.
