Introduction

The SparkFun 2D Barcode Scanner Breakout is a nifty little breakout board featuring the DE2120 barcode scanner module from DYScan. The DE2120 reads 20 different barcode symbologies (both 1D and 2D) using a camera coupled with on-board image processing to identify and decode everything from UPC codes to QR codes. The module also features two LEDs: one for illumination and one to project the red line for "aiming" that you're used to seeing from laser-based scanners.

The breakout makes it easy to use the scanner module by connecting the scanner's USB serial output to a USB-C connector. The breakout also includes a standard 0.1"-spaced PTH header for the power, serial UART, trigger and status output connections. On top of that, we've added a trigger button, buzzer and status LED connected to the appropriate drive circuits to easily initialize scans and receive feedback from scanning barcodes.
