The LCD2S-162YHY is a Serial LCD Character Display Module with a high speed
SPI/I2C serial bus. The LCD display is a 2x16 character STN yellow/green display with a yellow/green LED backlight, and is RoHS compliant. For convenience the I2C and SPI signals are available via a Micro Match type connector, and a
standard 2.54mm, 2x5 row pin header. Most new Modtronix SBC boards have Micro Match connectors, and
