Description 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 results 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 framework...

TR-72D RF range RF range strongly depends on the following design aspects:  Hardware:  Construction of the devices (especially TR location within the device, PCB layout, ground planes, conductive areas and bulk objects such as metallic parts and batteries in the nearest surroundings, with respect to possible reflections and counterpoise effect). To achieve an efficient range and reliable connectivity, no parts impacting the range must be placed close to the built-in meander antenna. Even non-conductive parts including a mainboard PCB under the antenna can significantly impact the range. ...

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-02 or KON-SIM-01. It is not allowed to connect wires to pads (except the M1, M2 and S1 pads) by soldering. Sealing In case of sealing or protecting TR modules against a harsh...
