Hardware Overview
How does it work?
Nano GPS 2 Click uses the Multi Micro Hornet module from OriginGPS, the smallest GPS module with an incorporated on‐board antenna element that is perfectly matched to receiver front‐end, frequency trimmed to GPS band, and Right‐Hand Circularly Polarized (RHCP). Module possesses dual-stage LNA (Low Noise Amplifier), SAW (Surface Acoustic Wave) filter, RTC crystal, GNSS SoC, and RF shield. GNSS SoC on a module is a hybrid positioning processor that combines many constellation configurations to provide a high-performance navigation solution such as GPS, GLONASS, GALILEO, BEIDOU, SBAS, QZSS, DGPS, and AGPS, allowing integration in embedded solutions with low computing resources. The ORG1510-MK05 module supports operational modes that provide positioning information at reduced overall current consumption. The availability of GNSS signals in the operating
environment will also factor in the choice of power management modes. The user can choose a mode that provides the best trade‐off of performance versus power consumption. Several power management modes can be enabled via a command, such as Full Power-Continuous Mode (for best GNSS performance), Power Save Mode (to optimize power consumption), and Backup Mode (low quiescent power state where receiver operation is stopped). Nano GPS 2 Click operates with received signal levels down to ‐167dBm and can be affected by high absolute levels of RF signals out of the GNSS band, moderate levels of RF interference near the GNSS band, and low levels of RF noise in the GNSS band. It uses a standard UART port and, besides the commonly used UART RX, TX, RTS, and CTS Nano GPS 2 Click, also has FON and WKP pins, which are routed to the PWM and AN pins of the mikroBUS™ socket,
respectively. Integrated GPS SoC incorporating a high-performance microprocessor and sophisticated firmware keeps positioning the payload off the host, allowing integration in embedded solutions with low computing resources. Innovative architecture can detect changes in context, temperature, and satellite signals to achieve a state of near-continuous availability by maintaining and opportunistically updating its internal fine time, frequency, and satellite ephemeris data while consuming mere microwatts of battery power. 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.
Features overview
Development board
Nucleo-64 with STM32G071RB MCU offers a cost-effective and adaptable platform for developers to explore new ideas and prototype their designs. This board harnesses the versatility of the STM32 microcontroller, enabling users to select the optimal balance of performance and power consumption for their projects. It accommodates the STM32 microcontroller in the LQFP64 package and includes essential components such as a user LED, which doubles as an ARDUINO® signal, alongside user and reset push-buttons, and a 32.768kHz crystal oscillator for precise timing operations. Designed with expansion and flexibility in mind, the Nucleo-64 board features an ARDUINO® Uno V3 expansion connector and ST morpho extension pin
headers, granting complete access to the STM32's I/Os for comprehensive project integration. Power supply options are adaptable, supporting ST-LINK USB VBUS or external power sources, ensuring adaptability in various development environments. The board also has an on-board ST-LINK debugger/programmer with USB re-enumeration capability, simplifying the programming and debugging process. Moreover, the board is designed to simplify advanced development with its external SMPS for efficient Vcore logic supply, support for USB Device full speed or USB SNK/UFP full speed, and built-in cryptographic features, enhancing both the power efficiency and security of projects. Additional connectivity is
provided through dedicated connectors for external SMPS experimentation, a USB connector for the ST-LINK, and a MIPI® debug connector, expanding the possibilities for hardware interfacing and experimentation. Developers will find extensive support through comprehensive free software libraries and examples, courtesy of the STM32Cube MCU Package. This, combined with compatibility with a wide array of Integrated Development Environments (IDEs), including IAR Embedded Workbench®, MDK-ARM, and STM32CubeIDE, ensures a smooth and efficient development experience, allowing users to fully leverage the capabilities of the Nucleo-64 board in their projects.

Accessories
Click Shield for Nucleo-64 comes equipped with two proprietary mikroBUS™ sockets, allowing all the Click board™ devices to be interfaced with the STM32 Nucleo-64 board with no effort. This way, Mikroe allows its users to add any functionality from our ever-growing range of Click boards™, such as WiFi, GSM, GPS, Bluetooth, ZigBee, environmental sensors, LEDs, speech recognition, motor control, movement sensors, and many more. More than 1537 Click boards™, which can be stacked and integrated, are at your disposal. The STM32 Nucleo-64 boards are based on the microcontrollers in 64-pin packages, a 32-bit MCU with an ARM Cortex M4 processor operating at 84MHz, 512Kb Flash, and 96KB SRAM, divided into two regions where the top section represents the ST-Link/V2 debugger and programmer while the bottom section of the board is an actual development board. These boards are controlled and powered conveniently through a USB connection to program and efficiently debug the Nucleo-64 board out of the box, with an additional USB cable connected to the USB mini port on the board. Most of the STM32 microcontroller pins are brought to the IO pins on the left and right edge of the board, which are then connected to two existing mikroBUS™ sockets. This Click Shield also has several switches that perform functions such as selecting the logic levels of analog signals on mikroBUS™ sockets and selecting logic voltage levels of the mikroBUS™ sockets themselves. Besides, the user is offered the possibility of using any Click board™ with the help of existing bidirectional level-shifting voltage translators, regardless of whether the Click board™ operates at a 3.3V or 5V logic voltage level. Once you connect the STM32 Nucleo-64 board with our Click Shield for Nucleo-64, you can access hundreds of Click boards™, working with 3.3V or 5V logic voltage levels.

Application Output via Debug Mode
1. Once the code example is loaded, pressing the "DEBUG" button initiates the build process, programs it on the created setup, and enters Debug mode.
2. After the programming is completed, a header with buttons for various actions within the IDE becomes visible. Clicking the green "PLAY" button starts reading the results achieved with the Click board™. The achieved results are displayed in the Application Output tab.

* # Description
* This example reads and processes data from Nano GPS 2 click.
*
* The demo application is composed of two sections :
*
* ## Application Init
* Initializes driver and wake-up module.
*
* ## Application Task
* Reads the received data and parses it.
*
* ## Additional Function
* - nanogps2_process ( ) - The general process of collecting data the module sends.
*
* @note
* Depending on the environmental conditions and the satellites availability
* it may take some time for the module to receive the position fix.
