Use C1M1-R2 on RPi5's GPIO

I want to attach my C1M1-R2 to my Raspberry Pi5 via its GPIO rather than the USB adapter. Are there any instructions on how to do it? The documents also differ whether the device need 3.3V or 5V. Thanks

Please check datasheet.

You can refer to the A1M8, it’s the same principle between them.
