Jetson J26 GPIO 3.3V ?

Hey we are using several GPIO on the J21 header @ 3.3V with 3.3V selected on the J24 header.
I’m wondering if we can set any gpio to output 3.3V on J26. They all seem to be 1.8V…
(J26 is the 30 pin gpio expansion 2)
J26 does have a power source thats 3.3V so is it possible to configure the gpio pins to give 3.3?

Obviously using a transceiver is an option but I’m avoiding that.

Thanks

Hi, please refer to carrier board schematic, only the ones routed to U7/U22 can be set to 1.8V or 3.3V.
