Hi,

I’ve connected a new qwiic button to a pi 4, but I’m not seeing the button’s i2c address with i2cdetect. I’ve tried different cables and swapping which connector faces the pi, but no joy. I have connected a gps module behind the button and it gets power.

Faulty button?

Thanks!

Can you share a photo of the setup? I presume you’ve enabled i2c on the Pi (as the GPS is working)
