Hardware Overview
How does it work?
iqRF Click is based on the DCTR-76DA, an RF transceiver from iqRF, operating in the 868/916 MHz frequency. The click is designed to run on a 3.3V power supply. It communicates with the target microcontroller over SPI or UART interface, with additional functionality provided by the following pins on the mikroBUS™ line: AN, RST, PWM, INT. DTCR-76DA is an RF transceiver operating in the 868/916 MHz license-free ISM (Industry, Scientific, and Medical) frequency band.
Its highly integrated ready-to-use design containing MCU, RF circuitry, serial EEPROM, and optional onboard antenna requires no external components. RF transceiver modules DCTR-72DA fit in the SIM connector. They are fully programmable under the IQRF OS operating system and allow the utilization of hardware profiles under the DPA framework. To upload application codes in DCTRs and configure DCTR parameters, a CK-USB-04A kit is intended. When
the application is uploaded to the IQRF, it can be put in the mikroBUS™ socket and communicate with it with MCU. 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
Arduino UNO is a versatile microcontroller board built around the ATmega328P chip. It offers extensive connectivity options for various projects, featuring 14 digital input/output pins, six of which are PWM-capable, along with six analog inputs. Its core components include a 16MHz ceramic resonator, a USB connection, a power jack, an
ICSP header, and a reset button, providing everything necessary to power and program the board. The Uno is ready to go, whether connected to a computer via USB or powered by an AC-to-DC adapter or battery. As the first USB Arduino board, it serves as the benchmark for the Arduino platform, with "Uno" symbolizing its status as the
first in a series. This name choice, meaning "one" in Italian, commemorates the launch of Arduino Software (IDE) 1.0. Initially introduced alongside version 1.0 of the Arduino Software (IDE), the Uno has since become the foundational model for subsequent Arduino releases, embodying the platform's evolution.

Accessories
Click Shield for Arduino UNO has two proprietary mikroBUS™ sockets, allowing all the Click board™ devices to be interfaced with the Arduino UNO board without effort. The Arduino Uno, a microcontroller board based on the ATmega328P, provides an affordable and flexible way for users to try out new concepts and build prototypes with the ATmega328P microcontroller from various combinations of performance, power consumption, and features. The Arduino Uno has 14 digital input/output pins (of which six can be used as PWM outputs), six analog inputs, a 16 MHz ceramic resonator (CSTCE16M0V53-R0), a USB connection, a power jack, an ICSP header, and reset button. Most of the ATmega328P 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 Arduino UNO board with our Click Shield for Arduino UNO, 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.
Software Support

*
* # Description
* IQRF Click carries the RF transceiver, operating in the 868/916 MHz frequency.
*
* The demo application is composed of two sections :
*
* ## Application Init
* Application Init performs Logger and Click initialization.
*
* ## Application Task
* Checks if new data byte has received in RX buffer ( ready for reading ),
* and if ready than reads one byte from RX buffer. In the second case,
* the application task writes message data via UART. Results are being sent
* to the Usart Terminal where you can track their changes.
