Status:
GNSS 14 Click is a compact add-on board that provides fast positioning capability to your application. This board features the MIA-M10Q, a standard precision GNSS module from u-blox. It has an exceptional sensitivity and acquisition time for all L1 GNSS signals, attributed to its integrated M10 standard precision low-power platform. The M10 platform supports concurrent reception of four GNSS (GPS, GLONASS, Galileo, and BeiDou). The high number of visible satellites enables the receiver to select the best signals. This maximizes position availability, particularly under challenging conditions like deep urban canyons. This Click board™ makes the perfect solution for the development of both acquisition and tracking devices and represents an ideal product for automotive, consumer, and industrial tracking applications.
GNSS 14 Click is fully compatible with the mikroBUS™ socket and can be used on any host system supporting the mikroBUS™ standard. It comes with the mikroSDK open-source libraries, offering unparalleled flexibility for evaluation and customization. What sets this Click board™ apart is the groundbreaking ClickID feature, enabling your host system to seamlessly and automatically detect and identify this add-on board.

GNSS 14 Click is based on the MIA-M10Q, a standard precision GNSS module from u-blox. Super-S (Super-Signal) technology offers great RF sensitivity and can improve the dynamic position accuracy with small antennas or in non-line-of-sight scenarios. It possesses the SMA antenna connector with an impedance of 50Ω, which can connect the appropriate GNSS antenna that MIKROE offers, like GPS&GLONASS Passive Antenna, for improved range and received signal strength. u-blox receiver includes a time pulse function that provides pulses with a configurable pulse period, pulse length, and polarity (rising or falling edge). It also features a backup voltage supply option. You can attach a battery to the GNSS 14 Click over the BAT connector.
GNSS 14 Click uses a standard 2-wire UART interface to communicate with the host MCU with commonly used UART RX and TX pins and a baud rate from 4800 up to 921600bps. You can also use an I2C interface for the same purpose, but only in slave mode with a maximum bit rate of 400kbps. In both cases, the UBX and NMEA protocols are supported.
The timepulse signal is available over the TP pin. The external interrupt signal over the EIT can be used for time mark feature, time aiding, and wake-up from power save modes. The RST pin allows you to reset the GNSS module with a Low logic state. In addition to these pins, this Click board™ also has one digital I/O pin marked IO6, with the possibility of defining the purpose of this pin depending on the user's needs. It is only necessary to emphasize that when assigning a different function to an I/O, ensure that the default function is disabled where applicable.
This Click board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. Also, it comes equipped with a library containing functions and an example code that can be used as a reference for further development.

We provide a library for the GNSS 14 Click as well as a demo application (example), developed using MIKROE compilers. The demo can run on all the main MIKROE development boards.
Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended), downloaded from our LibStock™ or found on Mikroe github account.
Library Description
This library contains API for GNSS 14 Click driver.
Key functions
gnss14_parse_gngga
This function parses the GNGGA data from the read response buffer.
gnss14_reset_device
This function resets the device by toggling the RST pin.
Example Description
This example demonstrates the use of GNSS 14 click board by reading and displaying the GNSS coordinates.
void application_task ( void )
{
if ( GNSS14_OK == gnss14_process( &gnss14 ) )
{
if ( app_buf_len > ( sizeof ( GNSS14_RSP_GNGGA ) + GNSS14_GNGGA_ELEMENT_SIZE ) )
{
gnss14_parser_application( app_buf );
}
}
}
The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended), downloaded from our LibStock™ or found on Mikroe github account.

Additional notes and informations
Depending on the development board you are using, you may need USB UART click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all MIKROE compilers.
This Click board™ is supported with mikroSDK - MIKROE Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
For more information about mikroSDK, visit the official page.
NOTE: Please be advised that any peripheral devices or accessories shown connected to the Click board™ are not included in the package. Check their availability in our shop or in the YMAN section below.
