The DYScan DE2120 is a compact 2D barcode scanner breakout board that reads 20 different barcode symbologies — both 1D (UPC, EAN, Code 128, etc.) and 2D (QR, Data Matrix, etc.). It uses an on-board camera with image processing to identify and decode barcodes, and features illumination and red line projection LEDs.

This revised version streamlines the design with a single USB-C connector that handles keyboard HID, USB HID, and CDC serial communication. The DE2120 can enumerate as all three protocols, including a standard COM port, eliminating the need for a separate USB-to-serial converter. A buzzer, status LED, and tactile trigger button are included on-board, and a 5-pin header provides direct TTL serial, power, and trigger access for embedded projects.
