GM861 1D/2D Barcode Reader Module with UART Interface, Stainless Steel Housing

The GM861 Barcode Reader Module The GM861 is a compact barcode reading module built around the same scan engine as the GM80X series. It reads all common one-dimensional barcodes with a high scan rate, and also handles two-dimensional barcodes at speed. Screen-based barcodes are no trouble either, so it suits modern retail, ticketing and access control environments where codes are often displayed on phones and tablets. Design and Installation The module uses a stainless steel housing with a threaded design, making installation straightforward. The mounting hole diameter is 25mm, and the unit is finished in silver. It connects via a UART interface, which keeps integration simple for embedded systems and OEM projects. Performance and Compatibility With support for both 1D and 2D codes, including QR codes, the GM861 offers flexible scanning in a single module. Its strong performance on linear barcodes makes it a dependable choice for fixed-mount scanning applications, while the ability to read from screens adds convenience for modern point-of-sale setups.
