Adafruit Prototyping Pi Plate Kit for Raspberry Pi
Adafruit Ultimate GPS HAT for Raspberry Pi 3/B+/Pi 2/Pi A+ - Mini Kit
It's 10PM, do you know where your Raspberry Pi is? If you had this GPS HAT, you would! This new HAT from Adafruit adds our celebrated Ultimate GPS on it, so you can add precision time and location to your Raspberry Pi Model Pi 3, Pi Zero, A+, B+, or Pi 2, 3, & 4
Here's the low-down on the GPS module:
-165 dBm sensitivity, 10 Hz updates, 99 search channels
GPS + GLONASS support
Built-in Real Time Clock (RTC) - slot in a CR1220 backup battery for 7-years or more of timekeeping even if the Raspberry Pi is off!
PPS output on fix, by default connected to pin #4
Internal patch antenna which works quite well when used outdoors + u.FL connector for external active antenna for when used indoors or in locations without a clear sky view
Fix status LED blinks to let you know when the GPS has determined the current coordinates
...all for under $30!
We spun up a HAT based on our Ultimate GPS, added a coin-cell holder for RTC usage, break-outs for all the Raspberry Pi's extra pins, and plenty of prototyping area for adding LEDs, sensors, and more.
