GM73 Barcode & QR Code Scanning Module

The GM73 is a high-performance barcode and QR code scanning module capable of reading common 1D and 2D codes from labels, paper, and screens in approximately 1 second. It uses advanced smart image recognition and decoding algorithms for fast, accurate scanning.

With onboard Micro USB and UART (TTL-232) interfaces, the module is easy to embed into custom projects. Parameters can be configured by scanning setup codes, simplifying integration and reducing development time.
