Overview

DE2120 2D Barcode Scanner​

The DE2120 is a compact barcode scanner module that reads 20+ symbologies — covering all common 1D formats (UPC, EAN, Code 128, Code 39) as well as 2D formats (QR Code, Data Matrix, PDF417, Aztec). It communicates over UART (TTL serial), supports three scanning modes (manual, continuous, and motion sense), and is straightforward to integrate using the provided Arduino library or MicroPython module.
