  • 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

  • uBLOX MAX-M8C Pico GPS Breakout with Chip Antenna

    0 out of 5

    This is new version of the popular pico break outboard, now with SCL & SDA. The board is assembled with a uBLOX MAX-M8C module, chip antenna and a decoupling capacitors.

    This board has VCC, GND and RX & TX, SCL & SDA for I2C.

    IMPORTANT : This module has no onboard voltage regulation so a clean regulated 1.8 – 3.6v power is required. If you want to link this to your microcontroller you must ensure it runs at 1.8 to 3.6v on the serial/I2C or you will risk damaging this module. Arduinos/PC Serial generally run at 5V so you will need a level converter.

    There is no provision for battery backup (V_BCKUP is hard tied to VCC).

    The MAX-8 family delivers all the benefits of the u-blox 8 GPS platform in a more compact form factor than ever before: high-sensitivity, intelligent power management.

    MAX comes in an ultra-compact, easy-to-mount 9.7mm x 10.1mm LCC package, and supports temperatures down to -40'C.

    Supports temperatures down to -40'C
    UART interface.
    RTC crystal for faster warm and hot starts
    Suitable for HAB Usage Max Altitude 50,000 meters / 164041 feet in Flight Mode.
    Supply Voltage 1.8 to 3.6V

    This module is designed to be as light as possible, weight is very light at 1.5g
