    NEW FOR 2020 Now with RAW Output & Hardware RTC


    The Uputronics Raspberry Pi GPS/RTC Expansion Board provides a modern multi GNSS GPS receiver and hardware RTC with quick no soldering required connection to all Raspberry Pi boards with the 2×20 header (the original Pi Model A/B are not supported). 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.


    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.
