Compact, fast and efficient bar code reader for embedded systems as well as PC based systems. Has both USB port and TTL serial ports. The USB port can be connected to the PC USB port and the codes are input just like a keyboard entry. With any text editor open you can scan a code and the code will appear in the editor. I also connected the UART port to the RX pin of the UNO and Mega and was able to display the code on the Arduino IDE serial monitor. Only 1 port of the bar code reader can be activated at any time, its either USB output or UART output, not both. There are various configurations which are achieved by reading the relevant QR code from the user manual. Unfortunately the user manual link in the product page provides a Chinese manual. I got the equivalent English manual by searching the internet for it. The price was a little high for me, but I had no other option for the time being. I am looking forward to getting the updated model GM66 which comes with an enclosure. Presently its not available in Banggood.

¡A prueba de tontos! Un poco de kit brillante. Pasamos todas las pruebas que lo hicimos; directamente de la caja. Pantallas del teléfono (brillante y tenue), papel b/n, fondo coloreado y código de barras coloreado.

fool-proof. brilliant bit of kit. Passed every test we set it; straight out of the box. Phone screens (bright & dim), b/w paper, coloured background and coloured barcode.
