Barcode L1D2D
1D/2D Barcode Scanner
- Overview
- Commands
- Samples
- On-Module Code
A 1D/2D barcode scanner that captures and decodes a wide range of formats — 1D: EAN-13/8, UPC-A/E, ISSN, ISBN, CodaBar, Code 128, Code 93, ITF-14/6, Interleaved 2 of 5, Code 39, Code 11, MSI-Plessey, GS1 Composite, GS1-Databar (RSS). 2D: QR Code, Data Matrix, PDF417. Scanning angle: roll 360°, pitch ±65°, yaw ±65°.
The module handles the imaging and decoding internally — your host code gets the decoded string with simple text commands over any supported interface, no image processing or codec libraries required.
Common uses: inventory checkout, asset tracking, library scanners, QR-driven kiosks, classroom data-capture projects, and any project that needs to read what's on a barcode without writing image-processing code.

Modules ship without cables to reduce waste. Some specialty boards include a USB cable; for the rest, see Cables to add cables to your order.
Commands this module accepts. See Samples for runnable code in popular host languages.
| Function | Description |
|---|---|
SetMode(m) | Set scanning mode (1: Trigger, 2: Continuous) |
Trigger() | Manually trigger barcode reading when in trigger mode |
DVer() | Check driver version |
Peek under the hood
The script below is this module's driver — it teaches the hardware how to respond to the commands listed above. It ships pre-loaded from the factory; most users never need to open it.

This sample runs in MicroBlocks on a any host board that's connected/tethered to this module, or a chain of modules. This module keeps its official DUELink firmware and module driver and responds to commands from the connected MicroBlocks-running host. New here? See the MicroBlocks page.
There are two ways to use it:
Open the full sample — the complete project (the module's library plus a ready-to-run example) opens directly on the MicroBlocks website.
Add just the libraries to your own project — copy the link, then in your MicroBlocks project click Add Library → Cloud and paste it. This loads this module's libraries into your project without replacing your current work.
Copy Library LinkCode that runs directly on this module's MCU. See how On-Module Code allows modules to run standalone.
- Script
- Arduino IDE
This example runs using the default DUELink Internal Engine using its Scripting Language, and it expects the module's driver to be loaded first, see the Commands Tab.
