GM65 is a high-quality 2D image scanning and recognition moduleThe built-in image scanning technology can be applied to a variety of applications. Whether it is a two-dimensional code or a one-dimensional bar code, it can be scanned in all directions. It can sensitively identify barcodes or on-screen display labels.GM65 provides various settings for customers in terms of functions. for example, the scan mode can be selected by key triggering or automatic continuous scanning.The communication mode can be selected as USB or virtual serial portThe barcode or QR code information scanned by GM65 can be directly displayed in the text input position such as WORD file.technical parameter:Optical system: CMOSCapture light source: 617nm LED (red light)Lighting source: 6500K LED (white light)Reading angle: 360 degree rotationDeflection +/- 60 degreeTilt +/- 65 degreeScanning angle: 34 degree (horizontal) 26 degree (vertical)Minimum contrast: 30%Resolution: greater or equal to 0. 1mm(4mil)Reading code system 1D: UPC/EAN, UPC/EAN with supplementals, BooklandEAN, ISSN, UCC Coupon Extended Code, Code 128, GS1-128, ISBT 128, Code 39, Code 39 Full ASCII, Trioptic Code 39, Code 32, Code 93, Code 11, Matrix 2 of 5, Interleaved 2 of 5, Discrete 2 of 5, Codabar, MSI, Chinese 2 of 5, GS1 DataBar variants, Korean 3 of 5, ISBT ConcatTwo-dimensional code 2D: QR Code, PDF417, Data MatrixVoltage: DC 5VCurrent: 120mA during scanning / 30mA during standbyInterface: USB, URATWorking temperature: Temperature: 0 Celsius~50 CelsiusStorage temperature: -40 Celsius~70 CelsiusWorking humidity: 10%~80%Ambient light: Ambient light: 0~86,000 luxcolour: blackMaterial: PCB + plasticsize: 46.5x27.8mmPackage Contents: 1 * USB cable1 * MX1.25*4P serial cable1 * Scan identification moduleOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
