Re: GPIO hardware with good support?

Emmanuel Dreyfus asked;

I would like to add a few GPIO pins to a machine that has none for now.
The possible extensions are SMB or USB. So I am looking for a SMB to
GPIO or USB to GPIO adapter that works nicely on NetBSD. Someone has
some harware to recommand?

Two possiblities come into my mind;

case 1. USB<>GPIO
case 2. I2C<>GPIO "IO expander"

For case 1 instance, I would suggest handy USB products like;

I have no specific product info of I2C IO expander this moment.
