QR/1D/2D Code Scanner V3.0 Barcode Scan Recognition Module with UART Serial Interface
QR/1D/2D Code Scanner V3.0 Barcode Scan Recognition Module with UART Serial Interface
The QR/1D/2D Code Scanner V3.0 is a high-performance barcode recognition module designed for seamless integration into embedded systems, DIY electronics, and commercial scanning solutions. Supporting a wide range of barcode formats including QR codes, 1D barcodes (such as EAN-13, Code128, UPC-A), and 2D codes (such as Data Matrix and PDF417), this compact scanner offers powerful decoding capabilities with fast response times and high accuracy.
Equipped with a UART (Serial Communication) interface, the module can easily connect to microcontrollers like Arduino, Raspberry Pi, STM32, and other development platforms, making it ideal for access control systems, vending machines, POS terminals, smart lockers, and automation projects.
Key Features:
Supports multiple barcode types: QR Code, 1D barcodes (EAN-8, EAN-13, Code128, Code39, UPC), and 2D codes (PDF417, Data Matrix)
High-speed recognition with excellent tolerance for low-quality and distorted codes
UART Serial Interface for easy communication with microcontrollers and embedded systems
Compact and lightweight design for flexible integration into space-constrained projects
Wide working voltage range (typically 3.3V to 5V) for versatile power compatibility
Plug-and-play functionality with simple serial commands for easy operation and development
