MIKROE-951 MCP23S17

16 bites I/O bővítő, két 8 bites PORT, 3.3V vagy 5V, SPI clock akár10 MHz

Expand click is an accessory board in mikroBUS form factor. It includes a 16-bit I/O expander MCP23S17 with SPI clock speeds up to 10 MHz for higher throughput applications. Three HARDWARE ADDRESS SEL jumpers allow you to configure board address and connect up to eight devices on the bus. Controller also supports interrupt-on-change feature. Board is set to use 3.3V power supply by default. Solder PWR SEL SMD jumper to 5V position if used with 5V systems.
