EXPAND 7 Click PID: MIKROE-4244 EXPAND 7 Click 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. 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. Specifications Type Port expander Applications 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. On-board modules EXPAND 7 Click is based on the CY8C9540A, 40-bit I/O expander with EEPROM, and 8 independently configurable 8-bit PWM outputs from Cypress Semiconductor.
