Carrier board

Hello,

I currently designing a carrier board for the TX2.

I need to use some GPIO now. I don’t know which pins are usable.

I would like to know FAN_TACH (PIN)can be left unconnected ? There’s a lot of pins in the design documentation that can not be disconnected without saying

When I designed UART, could RTS and CTS not be connected?

Thanks

Hi, please check the pinmux sheet for which pin can be set as GPIO, and check the OEM DG to get how to deal with the unused pins.
