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

Fusion for ARM v8 is a development board specially designed for the needs of rapid development of embedded applications. It supports a wide range of microcontrollers, such as different ARM® Cortex®-M based MCUs regardless of their number of pins, and a broad set of unique functions, such as the first-ever embedded debugger/programmer over WiFi. The development board is well organized and designed so that the end-user has all the necessary elements, such as switches, buttons, indicators, connectors, and others, in one place. Thanks to innovative manufacturing technology, Fusion for ARM v8 provides a fluid and immersive working experience, allowing access anywhere and under any

circumstances at any time. Each part of the Fusion for ARM v8 development board contains the components necessary for the most efficient operation of the same board. An advanced integrated CODEGRIP programmer/debugger module offers many valuable programming/debugging options, including support for JTAG, SWD, and SWO Trace (Single Wire Output)), and seamless integration with the Mikroe software environment. Besides, it also includes a clean and regulated power supply module for the development board. It can use a wide range of external power sources, including a battery, an external 12V power supply, and a power source via the USB Type-C (USB-C) connector.

Communication options such as USB-UART, USB HOST/DEVICE, CAN (on the MCU card, if supported), and Ethernet is also included. In addition, it also has the well-established mikroBUS™ standard, a standardized socket for the MCU card (SiBRAIN standard), and two display options for the TFT board line of products and character-based LCD. Fusion for ARM v8 is an integral part of the Mikroe ecosystem for rapid development. Natively supported by Mikroe software tools, it covers many aspects of prototyping and development thanks to a considerable number of different Click boards™ (over a thousand boards), the number of which is growing every day.

Application Output

After pressing the "FLASH" button on the left-side panel, it is necessary to open the UART terminal to display the achieved results. By clicking on the Tools icon in the right-hand panel, multiple different functions are displayed, among which is the UART Terminal. Click on the offered "UART Terminal" icon.

UART Application Output Step 1

Once the UART terminal is opened, the window takes on a new form. At the top of the tab are two buttons, one for adjusting the parameters of the UART terminal and the other for connecting the UART terminal. The tab's lower part is reserved for displaying the achieved results. Before connecting, the terminal has a Disconnected status, indicating that the terminal is not yet active. Before connecting, it is necessary to check the set parameters of the UART terminal. Click on the "OPTIONS" button.

UART Application Output Step 2

In the newly opened UART Terminal Options field, we check if the terminal settings are correct, such as the set port and the Baud rate of UART communication. If the data is not displayed properly, it is possible that the Baud rate value is not set correctly and needs to be adjusted to 115200. If all the parameters are set correctly, click on "CONFIGURE".

UART Application Output Step 3

The next step is to click on the "CONNECT" button, after which the terminal status changes from Disconnected to Connected in green, and the data is displayed in the Received data field.

UART Application Output Step 4

Code example

This example can be found in NECTO Studio. Feel free to download the code, or you can copy the code below.

 * \file 
 * \brief NanoGps2 Click example
 * # 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.
