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 2x20 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. 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.
