SparkFun 2D Barcode Scanner Breakout

The SparkFun 2D Barcode Scanner Breakout is a versatile, all-in-one scanning solution built around the powerful DYScan DE2120 module. It takes the capabilities of an industrial imaging scanner, which are typically plagued by finicky flat-flex cables, and breaks them out into a user-friendly USB-C board. Whether you need to scan standard UPCs for a point-of-sale system or decode complex QR codes for an embedded project, this board makes it plug-and-play.

Scanner Capabilities

This breakout is far more than a simple light sensor! It features a camera with onboard image processing to identify and decode 20 symbologies (1D and 2D). Additionally, it works just like the laser scanners you see at the grocery store, but adds the intelligence to read 2D matrix codes from screens or paper.

• Universal Decoding: This scanner reads everything from standard UPC/EAN product codes to complex QR, Data Matrix, and Aztec codes.
• Dual-LED System: Features a white LED for scene illumination and a red LED that projects a distinct "aiming line" for precision scanning.
• Instant Feedback: We added a buzzer and status LED directly to the board, so you get immediate audio-visual confirmation of every successful scan.

Smart Performance

The module can be configured either by using the serial interface or by scanning command barcodes found in the Settings Manual, and is designed for two distinct use cases:

1. USB Mode (Plug-and-Play): Connect it via USB-C to any computer. It can be enumerated as a Keyboard (typing data directly into your cursor), a HID device, or a Virtual COM port.
2. Embedded Mode (TTL Serial): For microcontroller projects (like Arduino or Raspberry Pi), use the 5-pin header to access the TTL serial pins, power, and trigger input directly.

This 2D Barcode Scanner Breakout is ideal if you need a reliable, easy-to-use module that handles both standard barcodes and modern QR codes without requiring complex code libraries on your microcontroller. The onboard processing handles all the heavy lifting for you.
