Description

The GM811-L barcode scanner module utilizes a high-performance CMOS image sensor operating in a 640×480 scan mode, providing the resolution necessary for accurate decoding of both 1D linear barcodes and dense 2D Matrix codes. Integrated white LED lighting ensures consistent illumination for reliable scanning under various ambient light conditions.

Designed for embedded and industrial applications, the module operates on a standard 5V DC supply with low current consumption. Its dual-interface design allows for direct USB connection or serial UART communication with microcontrollers, PLCs, and single-board computers, facilitating deployment in point-of-sale systems, inventory management, and automated logistics.

Key Features

  • High-efficiency CMOS imaging sensor with 640x480 pixel resolution.
  • Dual communication interface support: USB 2.0 and asynchronous serial UART.
  • Integrated white LED illumination system for consistent scan performance.
  • Visual status indicators: green LED for power-on, blue LED for successful scan confirmation.
  • Optimized for low power consumption, drawing approximately 70 mA at 5V.
  • Robust construction suitable for integration into commercial and industrial equipment.
  • Wide symbology support covering major 1D and 2D barcode standards.

Applications

  • Integration into self-service kiosks and point-of-sale (POS) terminals for retail.
  • Automated inventory tracking and warehouse management systems.
  • Embedded scanning in manufacturing lines for part identification and traceability.
  • Library and document management systems for asset tracking.
  • Mobile data collection devices and handheld terminals for field service.

Frequently Asked Questions

What are the communication interfaces on the GM811-L scanner?

The GM811-L module provides two primary interfaces: a USB 2.0 port for direct connection to PCs or embedded hosts, and an asynchronous serial UART (TTL-level) for direct integration with microcontrollers like Arduino, Raspberry Pi, or industrial PLCs. You can use either interface based on your system's requirements.

What is the operating voltage and power requirement?

The module requires a stable 5V DC power supply. Under typical operation, it draws approximately 70 mA. Ensure your power source can provide clean 5V power to avoid communication errors or failed scans.

How do I know if a scan was successful?

The module provides visual feedback via two LEDs. A steady green LED indicates the unit is powered on. Upon a successful barcode decode, a blue LED will illuminate momentarily. The decoded data is then transmitted via the active interface (UART or USB).

What types of barcodes can this scanner read?

It supports a comprehensive range of 1D linear barcodes (e.g., Code 128, Code 39, EAN-13, UPC-A) and 2D Matrix codes (e.g., QR Code, Data Matrix, PDF417). It does not support Direct Part Mark (DPM) codes etched or dot-peened directly onto surfaces.

What is the effective scanning distance?

The GM811-L model is specified for a reading distance range from 7 cm (minimum focus distance) up to 50 cm, depending on barcode size and print quality. Optimal performance is typically achieved within 10-30 cm under good lighting conditions.
