  • Raspberry Pi GPS/RTC Expansion Board

    0 out of 5

    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.

  • Raspberry Pi+ GPS Expansion Board

    0 out of 5

    This is an GPS expansion board designed specifically for the both the version 1,2 and 3 Raspberry Pi+ Models.

    This board is designed for applications that use a GPS connected via the serial ports to the Raspberry Pi such as timing applications or general applications that require GPS information. To facilitate PPS the time pulse output is connected to a GPIO so you can utilize this board to give NTP PPS discipline. PPS does not work without an antenna.

    This board is equipped with the latest Ublox MAX-M8Q positioning module and high quality filtering capacitors and inductors throughout. The MAX-M8Q features a RTC Crystal, very low power usage and high performance. Although not a true timing module it is more than adequate for a Pi based NTP Server. Its worth noting the module can, with a serial command, be placed in “Stationary” dynamic mode which is the default mode for the much more expensive timing modules.

    The board features an SMA connector for an active patch antenna (see related products) power and PPS LED's. On the top is a super capacitor which can be used to retain any custom settings in the event of power loss (If the module is commanded to do so ). The MAX-M8Q is connected via serial to the Pi and the PPS is connected to GPIO18 (pin 12).

    A 2×20 way header is supplied and 2 suitable standoffs providing a very robust solution. The board follows Raspberry Pi's HAT physical layout with camera and display port notches. It is possible to stack additional HAT's on top of this board with the stacking header.

    To use this board to make a Stratum 1 NTP Server please follow these instructions here : http://ava.upuaut.net/?p=726

    Datasheet available here

    For the communication protocol see the u-blox 8 / u-blox M8Receiver DescriptionIncluding Protocol Specification.

    (The command to save settings is CFG-CFG)
