Pico Explorer breakout pinout

Maybe it’s me, but I can’t find any reference to which way round to plug breakouts into the slots on the Pico Explorer base. Should they be plugged in with the positive supply rail on the Pico side, or the other way round with the ground pin nearest the Pico? I see they are polarity protected, so I’d hope they would survive either way round, but I guess they’ll only work when plugged in correctly!


Component side facing you, + towards the Pico.
