Key Features:
- Selectable RF band 868 / 916 MHz, multiple channels
- Based on the DCTR-76DA RF transceiver from IQRF
- Point-to-point or network wireless connectivity, Telemetry, AMR (automatic meter reading), WSN (wireless sensor network), Building automation, Street lighting control, etc.
- mikroBUS: SPI, UART, Analogue and GPIO Interfaces
The IQRF Click Board™ is based on the DCTR-76DA RF transceiver, operating in the 868/916 MHz frequency. The Click Board™ 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.

Module Features
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.
How Does The IQRF Click Board™ Work?
RF transceiver modules DCTR-72DA fit in the SIM connector. They are fully programmable under IQRF OS operating system and allow to utilize hardware profiles under DPA framework.
To upload application codes in DCTRs and configure DCTR parameters, CK-USB-04A kit is intended. When the application is uploaded to the IQRF it can be put in microBUS™ socket and communicate with it with MCU.

Code Snippet
This code snippet contains receiver and transmitter code for the IQRF Click Board™ working with the Thermo K Click Board™. When in transmit mode, MCU reads the temperature from Thermo K and if a certain threshold has been reached, byte data is sent to IQRF board via UART communication. Then, IQRF is broadcasting that byte to every other IQRF within range. Every Other IQRF click board is receiving that byte via RF communication and sending data to his local MCU via UART. Every event is displayed on easyTFT.
