Description

The Grow GM861 barcode scanner module utilizes a high-performance CMOS imaging sensor to capture and decode a wide array of 1D and 2D symbologies. Its 640×480 pixel resolution ensures reliable reading even on small or low-contrast codes. The module outputs decoded data via a selectable UART (TTL-level) or USB 2.0 interface, making it compatible with microcontrollers like Arduino, Raspberry Pi, and industrial PLCs.

Engineered for continuous operation in commercial and industrial environments, the GM861 features a green LED indicator for positive read confirmation. Its optical system is optimized for a reading distance of 5 to 30 centimeters, with generous pitch and yaw tolerances to accommodate varied mounting angles and product orientations on assembly lines or point-of-sale systems.

Key Features

  • Versatile Code Support: Reads major 1D codes (Code 128, Code 39, EAN-13, UPC-A) and 2D codes including QR codes.
  • Dual Interface Flexibility: Offers both UART serial (3.3V TTL) and USB HID/CDC interfaces for plug-and-play compatibility.
  • Optimized Optical Engine: CMOS sensor with integrated illumination provides consistent performance across the specified reading range.
  • User Feedback: Integrated green LED provides immediate visual confirmation of a successful scan.
  • Compact Form Factor: Small footprint and lightweight design enable integration into handheld devices or fixed-mount systems.
  • Low Power Consumption: Operates from a single 3.3V supply, drawing a maximum of 70mA, suitable for battery-powered applications.

Applications

  • Retail Point-of-Sale (POS) Systems: Integrated scanning for product checkout and inventory management.
  • Industrial Automation & Logistics: Track parts, packages, and pallets on conveyor belts and sorting lines.
  • Embedded Kiosks & Vending Machines: User interaction via QR code scanning for payments or information access.
  • Library and Asset Management: Rapid identification of books, equipment, or tools tagged with barcode labels.
  • Mobile Data Collection Devices: Portable inventory scanners and handheld terminals for field service.

Frequently Asked Questions

What are the communication interfaces on the GM861 scanner?

The GM861 module provides two primary interfaces: a UART serial port operating at 3.3V TTL logic levels (Tx, Rx, GND) and a standard USB 2.0 port. The UART interface is ideal for direct connection to microcontrollers like Arduino or ESP32, while the USB interface can emulate a keyboard (HID) or virtual COM port for plug-and-play use with PCs and single-board computers.

What is the operating voltage and power consumption?

This scanner module requires a 3.3V DC power supply and draws a maximum current of 70mA during active scanning. It is important to use a stable 3.3V source, as the logic levels for the UART interface are also referenced to this voltage. Exceeding 3.3V on the VCC or data lines may damage the module.

What types of barcodes and QR codes can it read?

The GM861 supports a comprehensive range of 1D linear barcodes including Code 128, Code 39, EAN-13, UPC-A, and Interleaved 2 of 5. For 2D codes, it is capable of reading QR codes. It does not support Direct Part Marking (DPM). The full list includes most common retail and industrial symbologies.

How do I know if a scan was successful?

The module features a green LED indicator that illuminates momentarily upon successfully decoding a barcode or QR code. This provides immediate visual feedback to the user. The decoded data string is simultaneously transmitted via the selected interface (UART or USB) to your host system for processing.
