SparkFun 2D Barcode Scanner Breakout

The SparkFun 2D Barcode Scanner Breakout is a compact and versatile device that utilizes the DE2120 barcode scanner module from DYScan. The DE2120 is capable of reading 20 different barcode symbologies, both 1D and 2D, through an integrated camera and on-board image processing system. This allows it to decode a wide range of barcodes, from UPC codes to QR codes. The module is equipped with two LEDs, one for illumination and the other to project the familiar red line seen from laser-based scanners.

The design of this breakout board simplifies the exploration of the DE2120's capabilities by eliminating the need for handling delicate flat flex cables. The scanner's USB interface is made accessible through an on-board USB-C connector. The module is equipped with a buzzer and status LED, which are connected through appropriate drive circuits, and a push button tactile switch on the "trigger" pin. For direct access to the TTL serial pins, power pins, and trigger input, a 5 pin header is provided for integration into your embedded project.

The DE2120 module can be configured either by using the serial interface or by scanning command barcodes found in the Settings Manual. The single USB-C connector allows for the transmission of all keyboard, HID, and serial protocols. The DE2120's unique feature is its ability to enumerate all three protocols, including a CDC serial driver, making the device appear as a standard COM port.

The SparkFun 2D Barcode Scanner Breakout comes with an array of features. It has a USB-C Connector for USB HID Interface and Virtual COM port, and is capable of reading 20 different symbologies. These include 1D symbologies such as UPC-A, UPC-E, EAN-8, EAN-13, Code 128, GS1-128, Code 39, Code 93, Code 11, Interleaved 2-of-5, Matrix 2-of-5, Industrial 2-of-5, Codabar, MSI, GS1 DataBar, and Datalogic 2-of-5. It can also read 2D symbologies such as QR Code, Data Matrix, PDF 417, Micro PDF 417, and Aztec Code.
