Enrich your device with LCD 2x16 or 4x20 character display using 4-wire SPI interface using the Serial LCD Adapter Board . Using a MCP23S17 16-bit remote bidirectional I/O port, this adapter board decreases the number of MCU pins required to run the display. The MCP23S17 module has high-speed (10 MHz) SPI interface that works well for applications that require higher throughput. The Serial LCD Adapter Board comes with a long flat cable featuring IDC10 female header connector that ensures compatibility with all MikroElektronika development boards. The user can also regulate the LCD contrast using the on-board potentiometer. It supports a 5V power supply only. The board has three hardware address pins that allow up to eight devices on the bus.
