The Lepton7 (Model R7100C), an embedded reader of the easy2read© product line, is an ultra compact reader for low power, high performance RAIN RFID applications.
With programmable output power from 10dBm to 30dBm, the reader can detect tags at more than 5 mt of distance (depending on antenna and tag dimensions).
Due to its low power consumption, the module is specifically designed to be easily integrated in battery powered devices.
The radio frequency core of the module is based on the Impinj E710 chipset that permits to achieve fast reading speed and to be used in dense reader and dense tag environments for top-class rated performances.
The compactness of the device and the surface mount technology allow to embed the Lepton7 inside the new small form factor industrial handhelds, smartphone accessories and other compact form factor devices.
The Lepton7 complies with and can operate in both European and US regulatory environments and, thanks to its multiregional capability, it’s ideal for integration in devices requiring compliance to different geographical regions.
The Lepton7 is pin-to-pin compatible with the Impinj RS1000 and RS500 and with the CAEN RFID Hadronmini module making it a perfect replacement for these devices.
