Adafruit Ultimate GPS HAT for Raspberry Pi A+/B+/Pi 2/3/Pi 4 - Mini Kit

NOTE: This is original version of the Ultimate GPS board, and has a  MT3339 (GPS only).  If you require a different version, please contact us!   

This new HAT from Adafruit adds their 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, 66 channels
• Only 20mA current draw
• 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
• We have received reports that it works up to ~32Km altitude (the GPS theoretically does not have a limit until 40Km)
• 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

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.

Comes as a fully assembled GPS + PCB and an additional 2x20 GPIO header. Some light soldering is required to attach the 2x20 GPIO header to the HAT but it's fast and easy for anyone with a soldering iron and solder. 

This HAT does not come with a 12mm coin battery! A CR1220 will let you use the real-time-clock capability of the GPS HAT.

Raspberry Pi -not- included!
