Description

EXT.IO is a GPIO Expander. With simple I2C commands it's possible to extend the GPIO pins for up to 8 extra GPIOs.

The EXT.IO Integrates the PCA9554PW chipset. This 8-bit I/O expander for the two-line bi-directional-bus (I2C) is designed for 2.3-V to 5.5-V VCC • with Open-Drain Active-Low Interrupt Output operation.

It provides general-purpose remote I/O expansion for most microcontroller families via the I2C interface.

I2C address by default is 0x27, unless changed manually.

It’s difficult to foresee the needs of your project from the start. EXT.IO is the perfect solution for expanding the number of IO. It allows you to add new features, logic, timing and sensing to already highly integrated designs.
