Mikroe Expand 17 Click
Mikroe Expand 17 Click is developed to expand the number of input/output pins in a system. The board is based on the Texas Instruments TCAL6408 8-bit I/O expander, which communicates through the I2C protocol.
The TCAL6408 supplies programmable output drive strength, latchable inputs, pull-up/pull-down resistors, and configurable open-drain or push-pull outputs, delivering flexible and enhanced I/O performance with minimal power consumption and reduced EMI. Furthermore, it supports independent logic and main power supplies, with the ability to select the main power source through a jumper.
The Mikroe Expand 17 Click is excellent for applications demanding additional I/Os, such as controlling switches, sensors, push buttons, and LEDs.
