No. You would be applying 3V3 to some signal pins of an unpowered Pi, which is Something Very Bad. Especially when GND is connected, or other signal pins are at Gnd potential.
- Is it safe to connect all their GPIO headers together in parallel excluding the +5v and +3.3v pins and then to a breadboard, HAT(+), or other device?
Thanks. That's just the info I needed.
