Jetson nano dev kit gpio pin max current

Hi. I have a Jetson nano Developer Kit and I want to know what is the maximum current that a single GPIO pin on it can supply? not much info in the datasheets. the SoM datasheet says 20uA but that’s not reasonable. some say 1mA or 2mA. is it related to the TXB0108 level shifter?

Hello,

Thanks for visiting the NVIDIA Developer forums! Your topic will be best served in the Jetson category.

I will move this post over for visibility.

Cheers,

The TXB0108 level shifters have auto-direction capabilities. They have very low driving capabilities and the auto-dir functionality is sensitive to pull-up or pull-down resistors.

On your own carrier board you should use those level shifters only if you absolutely need the auto-dir functionality.
For your devkit you should use 74lvc buffers for buffering the outputs. 74lvc541a has 8 outputs an a single chip. 74lvc1g17/2g17/3g17 have one to three gates. LVC logic can supply ±24mA on each output with a maximum of about 100mA per chip.

Ah! Yeah … Thanks
