Expand 17 Click Board™ - 8-Bit I/O Expander Board for Enhanced System Control

Expand 17 Click Board™ is a powerful solution for electronic design engineers seeking to expand their system's input/output capabilities. Based on the TCAL6408 8-bit I/O expander from Texas Instruments, this compact board communicates via the I2C protocol, offering seamless integration with mikroBUS™ compatible systems.

The board's versatility shines through its programmable features, including adjustable output drive strength, configurable pull-up/down resistors, and the option for open-drain or push-pull outputs. These advanced capabilities ensure enhanced I/O performance while minimising power consumption and electromagnetic interference.

Expand 17 Click Board™ supports independent logic and main power supplies, with a selectable main power source via an onboard jumper. This flexibility allows for optimal power management in various application scenarios. The board's I2C interface supports clock frequencies up to 1MHz, while the configurable I2C address adds to its adaptability.

Designed for professional engineers, Expand 17 Click Board™ comes equipped with mikroSDK open-source libraries and example code, facilitating rapid development and customisation. The innovative ClickID feature enables automatic detection by compatible host systems, streamlining the integration process.

Whether you're working with switches, sensors, push-buttons, or LEDs, Expand 17 Click Board™ offers a reliable and efficient solution for expanding your system's I/O capabilities, making it an invaluable tool for electronic design projects.
