The SparkFun 2D Barcode Scanner Breakout features the DE2120 camera-based scanner module, capable of reading 20 different barcode symbologies — from UPC and QR codes to Data Matrix and PDF 417. Onboard image processing handles decoding automatically, with illumination and aiming LEDs built in.

The breakout exposes the scanner's USB interface via a USB-C connector (HID keyboard, virtual COM port, and CDC serial all over one cable) and provides a 5-pin TTL serial header for embedded integration. A buzzer, status LED, and trigger button are included on the board. Configuration is done via serial commands or by scanning barcodes from the settings manual.
