I wish an I/O expander with i2c

I wish an I/O expander with i2c such as the NXP PCA9502 as an Xadow Modul. the Xadow requires a possibility of additional I / O pins. This can make the Xadow more popular because he would be more flexible. the i2c address may be set via solder joints on the back.

greeting,
