The GM865 barcode read module with excellent performance scan engine can not only easily read various types of one -dimensional barcodes, but also read the QR code at high speed. It has a very high scanning rate for linear barcodes. Barcodes can also be easily scanned. Adhering to the advanced barcode decoding algorithm of the GM80X series barcode reading module, it can be very easy and accurately read to read the barcode symbols, which greatly simplifies the difficulty of the development of barcode reading products. The parameter configuration of the function can be put into use in most cases without adjusting. Compatible with USB and TTL-232 interface. With buzzer for reminding you that the scanning successfully or not. Compatible with USB and UART interface.
