iDTRONIC M500 Embedded SMT Module UHF

Ultra-compact SMT UHF RFID reader module for fast PCB integration

The Embedded SMT Module UHF M500 is a high-performance UHF RFID reader module designed for direct surface-mount (SMT) assembly on your PCB. With a compact, clipper-sized footprint, it enables rapid integration into space-constrained devices such as handhelds/PDAs and desktop RFID equipment, helping reduce development effort and simplify production.

Built on the latest Impinj reader chipsets (E310 / E510 / E710, variant-dependent), the M500 supports EPC Class 1 Gen2 / ISO 18000-63 and operates across the global UHF band (840–960 MHz). A single mono-static 50 Ω RF port (optionally via IPEX) supports adjustable output power up to 27 dBm, enabling reliable reading performance for embedded applications.

An integrated temperature measurement supports stable operation in compact enclosures, while broad baud-rate support and GPIO make it easy to connect peripherals and integrate into your system architecture.
