Expand 15 Click is a compact add-on board that contains a multi-channel I/O expander. This board features the TCAL6416, a general-purpose I/O expansion for most microcontroller families from Texas Instruments. The TCAL6416 comes in one P-port configuration and allows easy addition of I/O through a standard I2C serial interface. P port is user-configurable to either a logic input or output by writing to the I/O configuration register bits. Its additional features are programmable output drive strength, pull-up and pull-down resistors, latchable inputs, maskable interrupt, interrupt status register, and programmable open-drain or push-pull outputs.
This Click board™ provides a simple solution when additional I/Os are needed for switches, sensors, push-buttons, LEDs, fans, and more.
