New! Version 3 comes with the latest module which has external antenna support and Pulse-Per-Second output

We carry a few different GPS modules here in the Adafruit shop, but none that satisfied our every desire - that's why we designed this little GPS breakout board. We believe this is the Ultimate GPS module, so we named it that. It's got everything you want and more:

• -165 dBm sensitivity, 10 Hz updates, 66 channels
  
• 5V friendly design and only 20mA current draw
  
• Breadboard friendly + two mounting holes
  
• RTC battery-compatible
  
• Built-in datalogging
  
• PPS output on fix
  
• Internal patch antenna + u.FL connector for external active antenna
  
• Fix status LED
  

...all for under $40!
