Description TR-78D 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 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 supports...

TR-78D RF range RF range strongly depends on the following design aspects:  Hardware:  Construction of the devices (especially TR location within the device, conductive areas and bulk objects such as metallic parts and batteries in the nearest surroundings, with respect to possible reflections and counterpoise effect).  Physical arrangement of devices (especially mutual orientations of antennas with respect to polarizations and radiation patterns)  Application software:  RF output power is selectable from 8 levels  To increase immunity to RF noise, incoming RF signal can be filtered...

TR-78D 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 Recommended panel mounting: TR-58Dx-RJ modules should be mounted with the O-ring Ø 25 mm x 1.5 mm (d1 x d2) by two screws. O-ring: Operating system See IQRF OS User's guide and IQRF OS Reference guide. DPA framework See DPA Framework technical guide. Application software See IQRF Quick start guide and IQRF application...
