  • You haven't even told us what the pins are or what connection type the scanner is ... serial? I2C? SPI? something else? – Jaromanda X Feb 2 at 0:19
  • The pins are the 5V GND,D1,DO,TXD..Am getting troubled in the the last three pins. The module is to be connected to arduino and LCD 12c.. – user52889 Feb 2 at 14:39
