Description

The GM66 barcode scanner module utilizes a high-performance imaging sensor to capture and decode a wide array of 1D and 2D barcodes. Its optical system, featuring a 617nm laser aimer and broad-spectrum 6500K white LEDs, ensures reliable reading under diverse lighting conditions from 0 to 85,000 lux. The module outputs decoded data via a selectable USB2.0 or TTL-level UART interface, making it compatible with both standard computers and 3.3V/5V logic microcontroller platforms.

Engineered for industrial and commercial durability, the scanner operates across an extended temperature range and features a compact, lightweight form factor suitable for space-constrained installations. Its flexible mounting and wide scan angles (Roll: 0-360°, Pitch: ±65°) facilitate integration into kiosks, vending machines, inventory tracking systems, and automated logistics equipment.

Key Features

  • High-precision scan engine with 0.10mm (4mil) minimum bar code resolution.
  • Dual communication interface: Standard USB2.0 (HID keyboard emulation) and configurable TTL UART (3.3V/5V logic).
  • Advanced illumination system with 617nm red laser aimer and 6500K white LEDs for consistent performance in ambient light from 0 to 85,000 lux.
  • Wide operating temperature range (-20°C to 55°C) and 5% to 95% non-condensing humidity tolerance.
  • Comprehensive symbology support for all major 1D linear and 2D Matrix barcodes, including postal codes.
  • Integrated user feedback via bi-color LED (red for power, blue for successful decode) and buzzer.
  • Compact and lightweight design (62.3 x 42.5 x 24.5 mm, 31g) for easy embedding into host devices.
  • Optimized depth of field from 25mm to 250mm with generous pitch and yaw scan angles.

Applications

  • Embedded Point-of-Sale (POS) and self-service kiosk systems.
  • Inventory management and asset tracking in warehouse automation.
  • Integration into vending machines and automated retail solutions for product identification.
  • Logistics and parcel sorting systems for label and waybill scanning.
  • Industrial automation for tracking work-in-progress and component serialization.

Frequently Asked Questions

What are the power requirements for the GM66 scanner module?

The GM66 requires a 5V DC power supply and draws approximately 120mA during operation. It can be powered via the USB connection or through the VCC and GND pins on its UART interface header, making it compatible with standard 5V Arduino, Raspberry Pi, and other microcontroller power rails.

How do I interface the GM66 with an Arduino or Raspberry Pi?

For microcontroller interfacing, use the UART (TTL) interface. Connect the module's TX pin to your microcontroller's RX pin, RX to TX, and provide 5V and GND. The module communicates at a default baud rate (configurable) to send decoded barcode data as serial text strings. The USB interface is for direct connection to a computer, emulating a keyboard.

What is the minimum barcode element size (resolution) it can read?

The GM66 has a high resolution of 0.10mm (4 mil), allowing it to reliably decode very high-density linear barcodes and small 2D Matrix codes. This makes it suitable for applications with limited label space or where printing resolution is constrained.

Can this scanner read barcodes on curved surfaces or at an angle?

Yes, the GM66 features wide scan angles (Pitch: ±65°, Yaw: ±60°) and a generous depth of field, allowing for flexible reading positions. Its robust illumination system helps maintain readability on curved or reflective surfaces, though optimal performance is achieved within the specified 25-250mm reading distance and recommended angles.

Is the GM66 suitable for industrial environments?

Yes, its operating temperature range of -20°C to 55°C and tolerance for 5% to 95% non-condensing humidity make it robust for many industrial and commercial settings. However, it is not rated for washdown or extreme environmental protection (IP-rated), so it should be housed appropriately in harsh conditions.
