How Does The GNSS 12 Click Board™ Work?
The GNSS 12 Click Board™ is based on the CAM-M8C, a concurrent GNSS chip antenna module from u-blox. The CAM-M8C is built on the high-performing M8 GNSS engine and utilizes simultaneous reception of up to three GNSS systems (GPS/Galileo together with BeiDou or GLONASS). It offers high sensitivity and minimal acquisition times while maintaining low power consumption and provides outstanding positioning accuracy even in GNSS-hostile environments. It also supports message integrity protection, geofencing, and spoofing detection with configurable interface settings to fit applications, such as industrial and automotive, easily.
The CAM-M8C communicates with the host MCU using the UART interface at 115200bps as its default communication protocol but also has other interfaces, such as SPI and I2C. The interface is selected by positioning SMD jumpers labelled COMM SEL in an appropriate position. Note that all the jumpers' positions must be on the same side, or the Click board™ may become unresponsive. In addition, this board also uses several mikroBUS™ pins. The reset pin routed on the RST pin of the mikroBUS™ socket provides the general reset ability, while the INT pin of the mikroBUS™ socket represents an external interrupt. An interrupt feature can be used for wake-up functions in the power save mode and aiding.
In the case of the primary supply failure, this Click board™ can use a backup supply voltage from a connected battery if you need the Click board™ to be a standalone device. Backup voltage supplies the real-time clock and battery-backed RAM and enables all relevant data to be saved in the backup RAM to allow a hot or warm start later. The module performs a cold start during a Power-Up sequence if the backup battery is not connected. In addition to precise positioning, the GNSS 12 Click also has an accurate timing signal indicated through an orange LED indicator marked as PPS.
Besides an integrated omni-directional GNSS chip antenna, the GNSS 12 Click possesses the N.FL antenna connector for connecting the appropriate active antenna offered by MikroE for improved range and received signal strength. Thanks to the LNA pin, routed to the PWM pin of the mikroBUS™ socket, it is possible to control the use of the external antenna through the MAX40200, and thus the power consumption in the power save mode. Also, for the simplest possible implementation of SMA antennas on these types of connectors, the MMCX-SMA Cable from our offer is recommended.
The GNSS 12 Click Board™ can only be operated from a 3.3V logic voltage level. Therefore, the board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used as a reference for further development.
