Zero Card compatible to Button SHIM?

[Mattias]

Hi folks,

I would like to connect a "Pimoroni Button SHIM" to the combination of RasPi 0W and the AI Zero card.
In the description to the card it says:
"Because we've used an IO expander to read the button states and drive the LED, you'll still have full access to all of your Pi's pins, assuming the I2C address (0x3f) doesn't clash."

Button SHIM: https://shop.pimoroni.com/products/button-shim
B.S. PinOut: https://pinout.xyz/pinout/button_shim

So, does anyone here know, what I2C address(es) the AI Zero uses, and if it would clash with the Button SHIM or not?

Thanks a lot
Mattias
