    Overview

    MICROSTACK is a framework of cross platform accessories that add functions to your designs through the use of cross platform module boards and platform specific adapter boards. Adapters to various platforms, starting with Raspberry Pi, add a common physical interface for connecting Microstack accessory module boards that are reuseable between designs and platforms.

    MICROSTACK GPS features the L80 ultra slim POT(Patch on Top) module with an embedded 15x15mm patch antenna, this MICROSTACK module adds GPS positioning functions to all platforms compatible with the Microstack framework. This space-saving design makes L80 become the perpect module for the miniature devices. Adopted by LCC package and integrated with patch antenna, L80 has exceptional performance both in acquisition and tracking.

    Combining advanced AGPS called EASY (Embedded Assist System) and proven AlwaysLocate technology, L80 achieves the highest performance and fully meets the industrial standard. EASY technology ensures L80 can calculate and predict orbits automatically using the ephemeris data (up to 3 days) stored in internal flash memory, so L80 can fix position quickly even at indoor signal levels with low power consumption. With AlwaysLocate technology, L80 can adaptively adjust the on/off time to achieve balance between positioning accuracy and power consumption according to the environmental and motion conditions.

    L80 supports automatic antenna switching function. It can achieve the switching between internal patch antenna and external active antenna. Moreover, it keeps positioning during the switching process. With its tiny design, high precision and sensitivity, L80 is perfectly suitable for a broad range of M2M applications such as portable device, automotive, personal tracking, security and industrial PDA, especially suitable for special applications, like GPS mouse and OBD.

    FAQs

    +
    -
    Can I directly interface the Microstack GPS module to connect and work with Raspberry Pi?
    No. Microstck boards do not interface directly with a SBC platform but through a base board like the MICROSTACK adapter board.
    +
    -
    How can I use the built-in logging of the Microstack GPS?
    The GPS unit can log data to its internal memory without the host computer running using the LOCUS logging system.

    How can I use the LOCUS logging system?
    Please refer to this document at: http://www.farnell.com/datasheets/1860443.pdf For instance The following Microstack™ Node Python functions provide a very
    easy way to use LOCUS logging:
    >>> gps.locus_query() # Query the status of the LOCUS logger
    >>> gps.locus_start() # Start the logger
    >>> gps.locus_stop() # Stop the logger
    >>> gps.locus_erase() # Erase all data items in the log
    >>> gps.locus_query_data() # Return a list of data items in
    the logger

    Where can I get related software?
    Please refer to this document at: http://www.farnell.com/datasheets/1860443.pdf For instance To install the Microstack™ Node libraries for Python 3, in a terminal, type the following command: sudo aptget install python3microstacknode. To install the gpsd standard tools enter the following command in a terminal: sudo aptget install gpsd gpsdclients pythongps.
