product line, are ultra compact readers for low power, high performance RAIN RFID applications. 

With programmable output power from 10 dBm to 25 dBm, the readers can detect tags at more than 2 m 
of distance (depending on antenna and tag dimensions). 

Due  to  their  low  power  consumption,  the  modules  are  specifically  designed  to  be  easily  integrated  in 
battery powered devices. 

The radio frequency core of the modules is based on the Impinj E310 IC 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 devices allows to embed the Lepton

3

x1 and Lepton

3

x4 inside industrial handhelds, 

smartphone accessories and other compact form factor devices. 

The  Lepton

3

x1  and  Lepton

3

x4  comply  with  and  can  operate  in  both  European  and  US  regulatory 

environments  and,  thanks  to  their  multiregional  capabilities,  they  are  ideal  for  integration  in  devices 
requiring compliance to different geographical regions. 

The  Lepton

3

x1  and  Lepton

3

x4  are  designed  on  the  basis  of  the  Lepton

3

  with  the  aim  to  facilitate  the 

integration  for  those  who  prefer  to  use  connectors  instead  of  automatic  manufacturing  required  by  the 
SMD form factor. In addition, Lepton

3

x4 is a turnkey solution for systems requiring up to 4 antenna ports.
