DwarfG2 UHF RFID Embedded Module

UHF RFID at 868/915 MHz is more and more replacing the classic HF RFID technology at 13.56 MHz due to a higher read range and lower costs for transponders. This trend leads to the fact that more and more developers have to work with UHF electronics, which is not an easy topic if you haven’t studied communication technology. A very simple way to integrate UHF RFID into your device without risk and shortest time-to-market is to use metraTec’s DwarfG2 UHF SMD module.

The compact module can be soldered directly to your mainboard as an SMD component. If you want to integrate it into a vending machine, label printer, or other devices with an embedded PC, you can also use a normal wire connector. With only 36 x 40 mm it fits into any machine with virtually no heat developed due to the automatic power save mode. Nonetheless, you will get a read range of up to 500 mm with a fitting antenna and transponder. Another feature is the high speed of the firmware when reading and writing data to a tag (approx 100 ms for a 96-bit EPC).
