GNSS 7 Click Board™

Product Code: MIKROE-3922

How Does The GNSS 7 Click Board™ Work? The GNSS 7 Click Board™ carries the NEO-M9N an ultra-robust meter-level GNSS positioning receiver module from U-blox. The mentioned module features onboard serial flash memory, message integrity protection, anti-jamming, anti-spoofing, and many more, making this Click board™ meet even the most stringent requirements in versatile industrial and consumer applications, such as UAVs, vehicles and assets tracking. For RF optimization, the NEO-M9N module features Advanced filtering algorithms mitigate the impact of RF interference and jamming, thus enabling the product to operate as intended. The GNSS 7 Click Board™ is designed mainly for using with NSS/GLONASS compatible active antennas. The NEO-M9 series utilizes concurrent reception of up to four GNSS (GPS, GLONASS, BeiDou, Galileo), recognizes multiple constellations simultaneously and provides outstanding positioning accuracy in scenarios where urban canyon or weak signals are involved. Note: Button battery 1.55V is provided with the GNSS 7 click The u-blox NEO-M9 modules can also benefit from the u-blox AssistNow assistance service.

The Online service provides GNNS broadcast parameters, e.g. ephemeris, almanac plus time or rough position to reduce the receiver's time to first fix significantly and improve acquisition sensitivity. Hardware Backup Mode - If the main supply voltage fails, and a battery is connected to V_BCKP, parts of the receiver switch off, but the RTC still runs providing a timing reference for the receiver. This operating mode enables all relevant data to be saved in the backup RAM to allow a hot or warm start later. The GNSS 7 Click Board™ supports both SPI and I2C/UART communication protocol configurations. Therefore, this Click board™ have communication interface selection jumpers, in order to allow the user to set whether to use SPI communication or combination. A USB interface (micro USB port), which is compatible with the USB version 2.0 FS (Full Speed, 12 Mbit/s), can be used for communication as an alternative to the UART. The USB port can be used as a power supply as well if you need the click board™ to be a standalone device. The GNSS 7 Click Board™ can operate with 3.3V MCUs only, it is set to work over the I2C and UART by default, and it is already equipped with the pull-up resistors. It is ready to be used as soon as it is inserted into a mikroBUS™ socket of the development system. SPECIFICATIONS Type GPS+GNSS Applications The GNSS 7 Click Board™ is suitable for asset tracking, for navigation devices based on GPS and GLONASS, road navigation devices, public transport, wearable devices, etc. On-board modules The NEO-M9N GNSS receiver module from u-blox with Active antena Key Features NEO-M9 series utilizes concurrent reception of up to four GNSS (GPS, GLONASS, BeiDou, Galileo) Interface GPIO,I2C,SPI,UART,USB Compatibility mikroBUS Click board size L (57.15 x 25.4 mm) Input Voltage 3.3V PINOUT DIAGRAM This table shows how the pinout on the GNSS 7 Click Board™ corresponds to the pinout on the mikroBUS™ socket (the latter shown in the two middle columns).
