Key Features

  • 16 I/O Pins that default to inputs at Power−Up, 5V Tolerant I/Os, high drive capability, individual I/O configuration, polarity inversion register, interrupt, and more
  • Based on the CAT9555 - general-purpose I/O expander from ON Semiconductor
  • Can be used for sensors, power switches, LEDs, pushbuttons, and fans
  • mikroBUS: I2C Interface

The Expand 14 Click Board™ is a compact add-on board that contains a multi-port I/O expander. This board features the CAT9555, a CMOS device that provides 16-bit parallel input/output port expansion from ON Semiconductor. The CAT9555 contains two 8-bit configuration ports (input or output), input, output, and polarity inversion registers, alongside an I2C-compatible serial interface. Any sixteen I/Os can be configured as an input or output by writing to the configuration register. It also features an active-low interrupt output, indicating to the host controller that an input state has been changed. This Click board™ provides a simple solution when additional I/Os are needed while keeping interconnections to a minimum in system monitoring applications, industrial controllers, portable equipment, and many more.

The Expand 14 Click Board™ is supported by a mikroSDK compliant library, including functions that simplify software development. This Click board™ comes as a thoroughly tested product, ready to be used on a system equipped with the mikroBUS™ socket.
