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 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.
