The�Expand 7 Click Board��is a compact add-on board that contains a multi-port I/O expander with bi-directional input/outputs or PWM outputs. This board features the�CY8C9540A, 40-bit I/O port expander with EEPROM and 8 independently configurable 8-bit PWM outputs from�Cypress Semiconductor. The CY8C9540A operates as two I2C slave devices, first as a multi-port I/O expander, and second as a serial EEPROM with 11 Kbyte address space. It has a user default storage, flexible I2C address configuration, and a programmable interrupt and reset function. This Click Board� can be used to monitor and control LEDs and system intrusion detection devices, but also as a storage for information such as error codes or board manufacturing data for diagnostic purposes.

The Expand 7 Click is supported by a�mikroSDK�compliant library, which includes functions that simplify software development. This�Click Board��comes as a fully tested product, ready to be used on a system equipped with the�mikroBUS��socket.
