Wide Input Shim and 12C/SDA/SCL pins

Support

Hi - The Wide Shim covers GPIO pins 3 (SDA) and 5 (SCL) on the Pi. Can you tell me if it uses them, or affects their usage in anyway?

Thanks

I couldn’t find a pinout for it. Raspberry Pi GPIO Pinout
I don’t see any shutdown buttons etc, looks to be just a buck converter. Those extra pins being used is I think just for stability. It likely only uses the +5V and Ground pins.
i2c is a shared bus anyway, you can still use it even if the shim uses it.
Run sudo i2cdetect -y 1 to see if there is anything using i2c.
You’ll get an error if i2c isn’t enabled. ;)
