The Hadronmini (Model R1271C), 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 27dBm, the reader can detect tags at more than 3 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 R2000 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 Hadronmini inside the new small form factor industrial handhelds, smartphone accessories and other compact form factor devices.
The Hadronmini is available in versions for both European and US regulatory environments and so it’s ideal for the integration in devices requiring compliance to different geographical regions.
The Hadronmini is pin-to-pin and SW compatible with the Impinj RS1000 and RS500 module making it a perfect replacement for these devices.
