The iDTRONIC RFID EMBEDDED UHF Module M620 is a high-performance UHF RFID module based on the IMPINJ New Generation reader chips (E310/E510/E710). This is an ultra-high frequency RF reader and writer chip with high sensitivity and long range reading distances combined with low power consumption and excellent performance. The RFID module was developed for the integation into RFID handheld devices, mobile applications or portable PCs.

The M620 UHF module has a MMCX antenna interface that supports a power output of max. 33 dBm, which enables it to rapidly read between 350 and 1,000 tags per second (depending on the IC Chip).

iDTRONIC’s hardware comes with a useful SDK for the development of controller, Linux or Windows based applications. In addition to the documentation, command protocols and source codes, the SDK includes a Windows-based demo application providing full functionality over all supported UHF RFID standards.
