Barcode Scanner Module 1D 2D QR Reader USB TTL232 Interface

The GM802-S Barcode Scanner Module The GM802-S is a compact barcode scanner module board designed for integration into a wide range of devices and systems. Operating on a DC3.3V power supply, it offers both USB and TTL232 interface options, providing flexibility for different hardware setups. This module reads 1D barcodes with ease and handles 2D barcodes at high speed, making it a versatile choice for developers and integrators. Scanning Performance With a reading distance of 5 to 30 cm, the GM802-S delivers reliable performance across a practical working range. It achieves high scanning speeds for linear codes and performs well even when reading barcodes displayed on paper or on-screen. This makes it suitable for applications where quick, accurate capture is essential, whether in retail, logistics, or access control systems. Actual reading performance may vary depending on the size and content of the code being scanned. Integration and Compatibility The module is designed for straightforward integration into existing hardware projects. The USB and TTL232 interfaces allow connection to a variety of host systems, while the compact board format suits space-constrained enclosures. The GM802-S supports PDF417 and QR code formats, broadening its usefulness across different barcode standards. This combination of compact design, flexible connectivity, and broad format support makes it a practical component for embedded scanning solutions.
