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 rat

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.
- geerlingguy 1y agoI think to Arduino, Uno just means 'Uno form factor, with shield pins in the same place'
- chimpontherun 1y agoWhich is kind of sad, since the Uno pinout is horrible for high-speed signals
- geerlingguy 1y agoFYI 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.
- chimpontherun 1y agoWell, 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
- the__alchemist 1y agoDepends on the MCU, but generally STM32 is 1.7-3.6V
- 0x457 1y agoSTM32 is 3v3 logic.
- the__alchemist 1y agoNot necessarily; see above (Or a datasheet)
- HeyLaughingBoy 1y agoYes, but many (most?) of them are 5V-tolerant.
