Description

The Uputronics Raspberry Pi GPS/RTC Expansion Board provides a modern multi GNSS GPS receiver and hardware RTC with no soldering required. It can be connected to all Raspberry Pi boards with the 40-pin (2x20) header.

New version 6.3 now with Flash & USB-C header for connection to PC or Mac!

Featuring PPS (Pulse per second) output to permit the use of the board for PPS disciplined NTP servers, RAW output available from the UBlox™ GPS module and twin super caps for GPS hot start/setting retention & maintaining RTC. Flash is also fitted for retention of settings and a USB header to connect to other devices is provided.

This board retains backwards compatibility with previous generation Uputronics Pi GPS boards.

With its features and ease of installation, we believe this is the ultimate GPS / RTC HAT for the Raspberry Pi!

We also have a great case available for the Raspberry Pi and GPS HAT combination, and you'll probably need an external antenna to get going!
