Please note, this HAT takes over the Raspberry Pi’s hardware UART to send/receive data to and from the GPS module. So, if you need to use the RX/TX pins with a console cable, you cannot also use this HAT. Instead, you’ll have to use a composite or HDMI monitor and keyboard to log in, or use ssh to connect over the network to your Pi.
- -165 dBm sensitivity, 10 Hz updates, 66 channels

- 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
