{"product_id":"the-long-range-eye-r200-uhf-rfid-reader-module","title":"The Long-Range Eye | R200 UHF RFID Reader Module, 2M Range (TTL UART + USB, 860-960MHz)","description":"\u003cdiv class=\"product-narrative\"\u003e\n\u003cp\u003e\u003cstrong\u003eMost hobbyist RFID modules ask you to press a tag flat against the antenna.\u003c\/strong\u003e That is not reading; that is tapping. The R200 module reads at up to two metres with a suitable antenna, which turns identification into something a person can walk past. For inventory tracking, access control prototypes, and asset tagging, that distance is the difference between a demo and a system.\u003c\/p\u003e\n\u003cp\u003eThe chip at the centre is the reason it works. The R200 UHF chipset is the workhorse of the RFID industry, proven in commercial production readers worldwide. This module brings that silicon to the workbench with both TTL UART and USB interfaces, so you can prototype from a laptop on day one and integrate into an embedded board on day thirty without changing hardware.\u003c\/p\u003e\n\u003cp\u003eThe included firmware speaks the standard R200 command set. That means code written during evaluation ports to a production board with minimal change. You design once and deploy across the whole product line, rather than rewriting the low-level layer every time the form factor shifts. For a maker building a smart shelf, a tool-tracking cabinet, or an automated inventory counter, that stability is worth more than a lower headline price.\u003c\/p\u003e\n\u003cp\u003eThe module operates across the full 860 to 960MHz UHF band, covering the global frequency allocations used by most commercial tag systems. It follows EPC Gen2 and ISO18000-6C, the two protocols that almost every passive UHF tag on the market complies with. Pair it with an external antenna in the 0 to 12dBi range, and the read distance scales with the antenna you choose.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eTwo metres is not a specification.
