Data Sheet

TR-72D Description (DC)TR-72D is a family of IQRF transceiver modules operating in the 868 MHz and 916 MHz license free ISM (Industry, Scientific and Medical) frequency band. Its highly integrated ready-to-use design containing MCU, RF circuitry, integrated LDO regulator, serial EEPROM, optional temperature sensor and optional on-board antenna requires no external components. Extended RF power result in higher RF range. Ultra low power consumption fits for battery powered applications. MCU with built-in operating system significantly reduces application development time. Optional DPA...

TR-72D Application Users have to ensure observing local provisions and restrictions relating to the use of short range devices by software, e.g. the CEPT ERC/REC 70-03 Recommendation and subsequent amendments in EU. See IQRF video tutorial set on www.iqrf.org/videos. Assembly TR-72Dx modules should be mounted in SIM connector. They are not intended for SMT reflow soldering. Recommended SIM connector: KON-SIM-01. Operating system See IQRF OS User's guide and IQRF OS Reference guide. DPA framework and DCTR See DPA Framework technical guide. Application software See IQRF Quick start guide and...
