GM861 Barcode Reader Module with LED Control Ring, UART Interface, 1D/2D QR Code Scanner, Silver

The GM861 Barcode Reader Module combines a compact metal housing with dependable scanning performance, making it a practical choice for embedded barcode reading applications. Built around an intelligent image recognition algorithm, the module reads both one-dimensional and two-dimensional barcodes with ease, including QR codes and barcodes displayed on phone or tablet screens. Design and Installation The GM861 features a threaded stainless steel housing with a silver finish, designed for straightforward panel mounting. The installation opening measures 25mm in diameter, allowing the module to sit flush within compatible equipment. This robust metal construction helps protect the internal optics during everyday use, while the threaded design keeps installation secure and simple. Scanning Performance Drawing on the scan engine used across the GM80X series, the GM861 handles linear barcodes with a high scan rate and reads 2D symbologies at speed. The advanced decoding algorithm simplifies the reading process, reducing the effort needed to integrate barcode capture into your own product design. Screen-based barcodes are also picked up reliably, which is useful for ticketing, loyalty programmes and mobile payment setups. Interface and Integration The module communicates over a UART interface, providing a straightforward connection for embedded systems and custom hardware projects. Whether you are developing kiosks, access control terminals, self-service machines or industrial handheld devices, the GM861 offers a compact, ready-to-integrate reading solution that keeps development time down.
