Metal 1D/2D Barcode Scanner Module with UART Interface, 25mm Mounting Hole

The GM861 is a compact barcode reading module built around a threaded stainless steel housing, designed for straightforward installation into a 25mm mounting hole. It combines a durable metal build with a silver finish, making it a practical choice for embedded scanning applications where reliability and a neat appearance matter. Reading Performance and Decoding Drawing on the scan engine used across the GM80X series, the GM861 handles both one-dimensional and two-dimensional barcodes with ease. It delivers a high scan rate for linear barcodes while also reading QR codes and other 2D symbols quickly. The module is equally comfortable scanning barcodes displayed on phone or screen, which adds flexibility in modern retail and access scenarios. Smart Image Recognition At its core, the GM861 uses an intelligent image recognition algorithm paired with an advanced decoding engine. This combination allows it to read barcode symbologies accurately and without fuss, reducing the effort needed when integrating scanning capability into your own product. The module communicates via a UART interface, keeping integration straightforward for developers and manufacturers alike. Easy Installation The threaded stainless steel casing is simple to fit, requiring only a 25mm cut-out. Once in place, the module sits securely and is ready to use, making it a dependable building block for kiosks, access control terminals, self-service devices and similar equipment.
