Waveshare Barcode Scanner Module (C) 640×480 USB/UART

Description

The Waveshare Barcode Scanner Module (C) is an embedded vision module engineered for reliable and fast optical code recognition. It utilizes an intelligent image processing algorithm to decode a wide range of 1D barcodes and 2D Matrix codes, including QR codes, with high accuracy. The module features a 640×480 resolution sensor and integrated visible light sources for illumination and aiming, ensuring consistent performance whether scanning printed labels or digital displays.

Designed for flexible system integration, it offers multiple communication protocols. By default, it operates as a USB HID keyboard, emulating keystrokes for immediate data entry into any PC. For more control, it can be configured as a USB virtual serial port or a standard UART device, making it ideal for microcontroller-based projects using platforms like Arduino, Raspberry Pi, or industrial PLCs. Its dual-voltage support (5V/3.3V) and moderate power consumption simplify power design for portable or fixed installations.
