The GM77-S barcode scanner module utilizes a high-performance CMOS imaging sensor to capture and decode both 1D linear barcodes and 2D Matrix codes with high contrast sensitivity. Its optical system is engineered for a wide depth of field, allowing reliable reading from very close proximity up to mid-range distances, even under varying ambient light conditions up to 100,000 lux.
Designed for embedded integration, the module provides a simple serial command interface via UART or plug-and-play USB HID connectivity. Its low-power design features separate operating and standby current modes, making it suitable for portable and battery-powered applications. The compact form factor and durable construction enable deployment in space-constrained and demanding industrial settings such as inventory management, kiosks, and automated logistics systems.
