    MIKROE GNSS 8 Click is a compact add-on board that provides fast positioning capability. This board features the LC79DA, a high-performance dual-band and multi-constellation GNSS module from Quectel Wireless Solutions. It supports L1 and L5 bands for GPS, Galileo, and QZSS, L1 band for GLONASS and BeiDou, as well as L5 band for IRNSS. This version of the LC79D module supports a standalone mode, has a built-in flash, and boots firmware from the flash to work independently. It also can achieve a high industrial level of sensitivity and accuracy with the lowest power consumption. This Click board™ is suitable for both acquisition and tracking and represents an ideal product for automotive, consumer, and industrial tracking applications.

    GNSS 8 Click is supported by a mikroSDK compliant library, which includes functions that simplify software development.

    GNSS 8 Click as its foundation uses the LC79DA, a high-performance dual-band and multi-constellation GNSS module from Quectel Wireless Solutions. It supports L1 and L5 bands for GPS, Galileo, and QZSS, L1 band for GLONASS and BeiDou, as well as L5 band for IRNSS. Compared with the GNSS modules working on the L1 band only, LC79DA dramatically increases the number of satellites involved in tracking and positioning, reducing signal acquisition time and improving positioning accuracy even when the GNSS signal is absent or compromised. The LC79DA is AIS-140 compliant, and its on-board LNAs and SAW filters serve to ensure better positioning under weak signal conditions and other harsh environments, providing it with better performance in anti-jamming.

    Besides Sleep and Standby operational modes, the LC79DA also has a Full-On mode that comprises tracking and acquisition modes. In acquisition mode, the module starts to search satellites and determine the visible satellites, coarse carrier frequency, and code phase of satellite signals. When the acquisition is completed, it will automatically switch to tracking mode. In tracking mode, the module tracks satellites and demodulates the navigation data from specific satellites.

    The LC79DA communicates with MCU using the UART interface with commonly used UART RX and TX pins as its default communication protocol operating at 115200 bps by default configuration to transmit and exchange data with the host MCU. It is also equipped with a USB type C connector, which allows the module to be powered and configured by a personal computer (PC) using FT230X, a compact USB to a serial UART interface bridge designed to operate efficiently with USB host controllers. Besides this bridge, it also possesses the RX/TX blue LED indicator that indicates whether the bridge is in RX or TX mode. The users can also use another interface such as I2C to configure the module and write the library by themselves.

    The REQ pin routed on the RST pin of the mikroBUS™ represents data availability indication used to indicate whether there is data available for reading, while the INT pin on the mikroBUS™ socket represents a standard interrupt feature providing user with feedback information. Next to these pins, this Click board™ also uses AP request to send pin labeled as APR, routed on the PWM pin of the mikroBUS™ socket, and RDY module status indication used in conjunction with APR pin. The high level of the APR pin notify the module that the AP has data to be sent, and its low level means that data transfer has been completed, while RDY is used to indicate whether the module is ready for communication with the AP. Also, this Click board™ has an additional yellow LED labeled as GNSS that shows one pulse per second synchronized to GNSS satellites.

    An onboard pushbutton labeled BOOT represents the StartUp mode control button. Pressing the button for about 100ms during the Power-Up sequence, the LC79DA module will enter the host mode, allowing the users to perform firmware download successfully. After the module enters host mode successfully, release the BOOT button. BOOT mode can also be achieved with external signal on BOOT CTRL header, on the same way as button. In addition, the additional header labeled as NSTB can be used both to access the Standby mode and to reset the module itself using an external signal.

    GNSS 8 Click possesses the SMA antenna connector with an impedance of 50Ω, which can be used to connect the appropriate active antenna for improved range and received signal strength.

    This Click board™ can operate with both 3.3V and 5V MCUs. A proper logic voltage level conversion is performed by the appropriate voltage level translator TXS0108E, while the on-board LDO, the LT1965, ensures that the recommended voltage levels power module. However, the Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.
