Waveshare 2D Codes Scanner Module (C), High Accuracy Barcode/QR Code Reader

Reading a barcode or QR code into an embedded project usually means either repurposing a camera module and running image-processing software, or wiring in a dedicated scanner module built specifically for the job - and this is the latter, purpose-built approach. It handles both traditional 1D-style and full 2D/QR codes with genuine high-accuracy scanning, making it suitable for inventory tracking, access control, or any automation project that needs to identify a scanned item or ticket without the processing overhead of running computer vision on a general-purpose camera feed.
