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

How to Request a PCB Layout / Design
- Send your complete schematic or diagram via our Facebook page.
- Our team will review your diagram carefully to understand the design scope and requirements.
- A detailed quotation will be provided based on:
-
- Design complexity
- Board size and number of layers
- Components and package types
- Special routing or manufacturing requirements
📌 Providing your diagram is essential so we can give you an accurate and fair quotation.
PCB Layout & Design Requirements
To ensure quality and accuracy, please note the following:
- All schematics must be clear, complete, and properly labeled
- Specify:
- Board dimensions (if available)
- Number of PCB layers
- Preferred components or footprints (if any)
- Hand-drawn, unclear, or incomplete schematics are not accepted
- Rush or urgent requests may incur additional charges
What’s Included in the Design Package
Each completed project includes the following deliverables:
✅ 2D PCB layout images
✅ 3D PCB render images
✅ PCB Gerber files (ready for fabrication)
