3117 and 3417/3419 RAIN RFID Reader Modules


    Impinj Connected CLR RGB LG

    TSL® have drawn upon years of industry leading mobile RFID experience to design and manufacture a family of high performance, energy efficient UHF RFID modules that can be easily integrated into handheld/mobile/battery powered devices or small, fixed reader applications.

    These highly configurable and flexible modules come with a range of RF modes to ensure optimal performance in even the most challenging environments.

    The compact and slim form factor of these modules provide flexible mounting options, supported by industry standard USB and serial UART port interfaces combined with four configurable 3.3V I/O lines.

    The 50 Ω MMCX Antenna Port(s) provide the freedom to specify an antenna perfectly tuned to your unique application. The class-leading 3117 and 3417/3419 RAIN RFID modules support multiple RF modes including High Speed Tag Acquisition Mode, High Sensitivity Mode and Dense Reader Mode (DRM). Software programmable output power allows the conducted output to be configured in 0.1 dBm steps from 1 dBm up to the regulatory maximum.

    The next generation Impinj E710 chip in the 3117 and 3417 sports cutting-edge hardware and the latest anti-collision recognition algorithms, enabling read rates of ≥ 1200 tags/s. The 3419 RAIN RFID Reader Module is our ultra high-sensitivity, flagship model, sporting a top-end Impinj E910 reader chip.

    TSL’s STORM RFID protocol (a sophisticated, parameterised set of commands that carry out multiple actions locally within the RFID module) makes embedded integration a breeze, reducing time-to market and development costs. Multiple complex tag commands can be stored across 10 memory banks and then executed by simple calls to each bank. This approach enables complex tag operations to be executed using simple pre-configured commands.

    TSL provides the free, comprehensive STORM Protocol SDK, allowing development in C, C# and Java languages on platforms including .NET, Android, Windows and Linux.
