SparkFun 2D Barcode Scanner Breakout v2

The SparkFun 2D Barcode Scanner Breakout v2 upgrades your barcode reading capabilities by integrating the highly capable DE2290D module from DYscan. This version of the Barcode Scanner Breakout upgrades to the DE2290D which now uses advanced CMOS image recognition technology paired with a 300 000-pixel global shutter camera!This combination delivers a highly accurate reading precision of 3mil (0.076mm) and decodes an extensive list of 1D and 2D symbologies. The module automatically adjusts its lighting brightness based on the distance to the target ensuring excellent reading performance whether you are scanning barcodes off printed paper merchandise packaging or digital screens.Scanner CapabilitiesThis breakout is far more than a simple light sensor! It features a camera coupled with onboard image processing to identify and decode more than 30 different symbologies (both 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.Embedded Access: For permanent installations a 5-pin header gives you direct access to the TTL serial pins power pins and the trigger input.Smart PerformanceLike the previous version the DE2290D 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:USB Mode (Plug-and-Play): All keyboard HID and serial data can be transmitted over the single USB-C connector. The DE2290D has the unique ability to enumerate all three protocols simultaneously including a CDC serial driver that makes the device appear as a standard COM port on your computer.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.The DE2290D adapts easily to your specific application through multiple supported working modes including Manual Auto Sense Continuous and Command control.
