STM32 MCUs are 3V3, not 5V right?

Arduino really isn't great with naming, a Uno can be an AVR or ARM based board, now either 3V3 or 5V based and also a SBC rather than just a MCU.

I think to Arduino, Uno just means 'Uno form factor, with shield pins in the same place'

    Which is kind of sad, since the Uno pinout is horrible for high-speed signals

      FYI the new Q has two 'high speed connectors' on the bottom side, for signals like CSI, HDMI, USB 3.1, etc.

      Haven't seen any examples of bottom 'high speed' shields yet, though. They said there would be some made available.

        Well, if all the interesting signals are on the mezzanine, what's the point of the Arduino form factor and pinout? Just to claim that they're supporting a widely used platform? Engineers can see through it.

        The more I look at it, the more it sounds like a platform designed by M&A team
