The Aura A033 is a desktop UHF RFID reader/writer developed by SeeMore IoT. Equipped with the latest Impinj E310 chip, it fully supports ISO18000-6C/EPC C1G2 protocols. The operating frequency covers FCC (902MHz–928MHz), ETSI (865MHz–868MHz), and CMIIT (920MHz–925MHz) bands. Output power can be flexibly adjusted from 5dBm to 30dBm (±1dB) in 1dB steps, meeting diverse application requirements for UHF tag inventory and read/write operations.   The device features a built‑in near‑field antenna with controlled read range, strong anti‑interference capability, and high stability/reliability. It communicates via a single USB interface (Type‑C) supporting USB‑to‑serial and USB keyboard emulation. The DR03A is widely used in smart retail, asset management, library/book lending, backend card issuance, medical devices, pharmaceutical management, and anti‑counterfeiting traceability.   Key Advantages Integrated next‑generation Impinj E310 chip Supports ISO18000‑6C/EPC C1G2 and Gen2X extended functions Selectable frequency bands: FCC, ETSI, CMIIT Supports FHSS (Frequency Hopping Spread Spectrum) or fixed‑frequency transmission High‑performance anti‑collision algorithm for reliable multi‑tag reading USB plug‑and‑play, no driver required; USB powered Keyboard emulation mode Returns tag RSSI and phase angle Tag data filtering Pre‑loaded with 16 sets of keys Online firmware upgrade Audible/visual indicators: buzzer, read LED, status LED
