Waveshare Barcode Scanner Module, for Reading 1D/2D Codes on Paper or PC Screen

• Simple operation, no need to understand complex image recognition algorithms
• Support the reading of general one-dimensional codes and two-dimensional codes such as Barcode and QR
• On-board micro USB and UART serial ports can be connected to computers or embedded devices for use
• Supports setting module parameters by scanning the 'configuration code'
• Onboard auxiliary light source for reading in complete darkness

Features A barcode QR code scanning and recognition module can quickly and accurately read 1D and 2D codes on paper or on the screen through an image intelligent recognition algorithm. Small in size, with on-board USB and UART interfaces, it can be directly connected to a computer for use, and can also be integrated into various devices.
