Mikroelektronika MIKROE-951 EXPAND Click Board MCP23S17 16-bit I/O Expander SPI 10 MHz

Technical description of the product (MIKROE-951):

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. Type: Port expander. Applications: Board is ideal for saving microcontroller pins, and expanding the number of input-output lines. On-board modules: 16-bit I/O expander MCP23S17. Key Features: High-speed SPI interface 10 MHz (max.). Low standby current: 1 µA (max.). Key Benefits: 16 GPIO pins divided into two 8-bit PORTs. Interface: GPIO, SPI. Input Voltage: 3.3V or 5V. Compatibility: mikroBUS. Click board size: M (42.9 x 25.4 mm).
