Product Code: MIKROE-4243

The?Expand 6 Click Board??is a compact add-on board that contains an I2C configurable multi-port I/O expander with independently configurable pins as bi-directional input/outputs or PWM outputs. This board features the?CY8C9520A, 20-bit I/O expander with EEPROM, and 4 independently configurable 8-bit PWM outputs from?Cypress Semiconductor. The CY8C9520A operates as two I2C slave devices, first as a multi-port I/O expander, and second as a serial EEPROM with 3 Kbyte address space. It has a user default storage, flexible I2C address configuration, and a programmable interrupt function that indicates input pin level changes and PWM state changes. 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.
