If you need more pins, GLCD or character LCD for your applications than the Serial LCD/GLCD Adapter Board is the best choice. It is connected to an LCD/GLCD via the on-board MCP23S17 serial port expander that uses SPI communication.
The Serial LCD/GLCD Adapter Board enables you to easily connect your GLCD 128x64px and LCD 2x16, 4x20 character displays to your board and save MCU pins. A 16-bit I/O expander MCP23S17 is provided on the board thus decreasing the number of MCU pins needed for running this display. Expander features SPI(tm) clock speeds up to 10 MHz for higher throughput applications. Board is equipped with a long flat cable with IDC10 female header connector, which is compatible with all mikroElektronika development boards.
