Hardware Overview
How does it work?
Nano LR Click is based on the EMB-LR1276S, a sub-1GHz wireless module that supports the LoRaWAN long-range wireless protocol based on the SAMR34 SiP from Embit. It offers a long-range spread spectrum communication with high interference immunity. Nano LR Click is ideal for various applications, such as IoT, home and building automation, wireless alarm and security systems, automated meter readings, industrial monitoring and control, and more. The EMB-LR1276S can be configured as an embedded microsystem or a simple data modem for
low-power applications in the 868MHz and 915MHz radio bands. It is equipped with up to 256 KB of Flash and up to 40 KB of SRAM, and it supports long-range and FSK modulation. Nano LR Click communicates with MCU using the UART interface with commonly used UART RX and TX pins with the hardware flow control pins UART CTS, RTS, RI (Clear to Send, Ready to Send, and Ring Indicator). Besides these pins, Nano LR Click also has GP1 and STAT pins, which are routed to the PWM and AN pins of the mikroBUS™ socket, respectively. STAT pin is also wired to a separate
LED indicator labeled STAT to enable quick and easy module status indication. Nano LR Click features the U.FL antenna connector with an impedance of 50Ω, so it can be equipped with the appropriate antenna that MIKROE offers. 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
EasyPIC v8 for PIC24/dsPIC33 is a development board specially designed for the needs of rapid development of embedded applications. It supports a wide range of 16-bit PIC24/dsPIC33 microcontrollers from Microchip and has a broad set of unique functions, such as the first-ever embedded debugger/programmer. 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, EasyPIC v8 for PIC24/dsPIC33 provides a fluid and immersive working experience, allowing access anywhere and under any circumstances. Each part of the EasyPIC
v8 for PIC24/dsPIC33 development board contains the components necessary for the most efficient operation of the same board. In addition to the advanced integrated CODEGRIP programmer/debugger module, which offers many valuable programming/debugging options and seamless integration with the Mikroe software environment, the board 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 HOST/DEVICE, USB-UART, CAN, and LIN are also
included, including the well-established mikroBUS™ standard, two display options (graphical and character-based LCD), and several different DIP sockets. These sockets cover a wide range of 16-bit PIC24/dsPIC33 MCUs, from the smallest PIC24/dsPIC33 MCUs with only 14 up to 28 pins. EasyPIC v8 for PIC24/dsPIC33 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.

Measuring a compact 50mm in length and featuring an SMA male connector, the Rubber Antenna GSM/GPRS Right Angle is a versatile and compact solution for your wireless communication needs.
IPEX-SMA cable is a type of RF (radio frequency) cable assembly. "IPEX" refers to the IPEX connector, a miniature coaxial connector commonly used in small electronic devices. "SMA" stands for SubMiniature Version A and is another coaxial connector commonly used in RF applications. An IPEX-SMA cable assembly has an IPEX connector on one end and an SMA connector on the other, allowing it to connect devices or components that use these specific connectors. These cables are often used in applications like WiFi or cellular antennas, GPS modules, and other RF communication systems where a reliable and low-loss connection is required.

Application Output via UART Mode
1. Once the code example is loaded, pressing the "FLASH" button initiates the build process, and programs it on the created setup.
2. After the programming is completed, click on the Tools icon in the upper-right panel, and select the UART Terminal.
3. After opening the UART Terminal tab, first check the baud rate setting in the Options menu (default is 115200). If this parameter is correct, activate the terminal by clicking the "CONNECT" button.
4. Now terminal status changes from Disconnected to Connected in green, and the data is displayed in the Received data field.
Software Support
Library Description
This library contains API for Nano LR Click driver.
Key functions:
nanolr_send_data
- This function sends data command depends on the chosen network protocol.nanolr_uart_isr
- This function reads response bytes from the device and sets flag after each received byte.nanolr_rsp_rdy
- This function checks if the response is ready.

*
* # Description
* This example reads and processes data from Nano LR clicks.
*
* The demo application is composed of two sections :
*
* ## Application Init
* Initializes the driver, and performs the click default configuration.
*
* ## Application Task
* Depending on the selected mode, it reads all the received data or sends a desired message
* every 2 seconds. All data is being displayed on the USB UART.
*
* ## Additional Function
* - nanolr_process ( ) - Waits until a new message is ready, then parses it and displays the message
* info on the USB UART.
