OverviewThis is a small 1D/2D codes reader, by using the intelligent image recognition algorithm, it will decode the barcode or 2D code on paper or screen, fast and accurately.Through the onboard USB and UART interface, it can be directly plugged into a computer, or be easily integrated to kinds of devices due to its small form factor.FeaturesEasy to use, requires no knowledge of image recognitionDecodes various common 1D/2D codes such as Barcode, QR code etc.Onboard micro USB and UART serial port, allows to connect with computers or embedded devicesConfigurable via scanning ‘configuration code’Onboard light source, works in the darkSpecificationsOperating voltage: 5VOperating current: 135mA (scanning), 58mA (standby), 2mA (sleep)Operating temperature: 0°C~60°COperating humidity: 5%~95% (Non-condensing)Communication interface: UART, USBDecodes 1D codes: Codebar, Code 11, Code 39/Code 93, UPC/EAN, Code 128/EAN128, Interleaved 2 of 5, Matrix 2 of 5, MSI Code, Industrial 2 of 5, GS1 Databar(RSS)Decodes 2D codes: QR code, Data Matrix, PDF417DOES NOT SUPPORT THE FORMAT FOR SCANNING RSA DRIVER’S LICENSELight source: whiteScan angels: roll 360°, skew ±65°, pitch ±60°Field of view: 28° (horizontal), 21.5° (vertical)Dimension: 53.3mm x 21.4mmWhat’s in the box?1 x WS Barcode Scanner ModuleResourcesWiki : www.waveshare.com/wiki/Barcode_Scanner_Module
