IQRF 2 click carries the DCTR-72DAT RF transceiver, 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, PWM.

Module features

DCTR-72DAT 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 the click works

The DCTR-72DAT module's highly integrated ready-to-use design containing MCU, RF circuitry, integrated LDO regulator, serial EEPROM, optional temperature sensor and optional onboard antenna requires no external components. 

It has extended RF power results in higher RF range. The ultra-low power consumption fits for battery powered applications. 

The module with a built-in operating system significantly reduces application development time. Optional DPA framework supports applications even without programming.



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.

To upload the firmware put the jumpers in the SPI position.

To use our LibStock library examples the jumpers need to be in UART position.
