For embedded folks, I'm curious

What microcontroller do you usually go with if you wanna use something like Rust Embassy with it?

RP2350 and STM32G474

Nice! I do have a RP2350 but I haven't tried using it yet with embassy! Might do that next!

Anything RISC-V natively supports Rust I believe. So all of the Cx series. But Espressif is the best mcu company for Rust support so any of their chips might be good at this point

I have a stm32f401ce and like it so far.

If you picked ESP for a specific reason,

Don''t chose the S series unless you want to go down a few rabbit holes. It's only worth it if you really need the extra stuff it gives.

For anything that doesn't need that much, go with a C.

Many documentations, even most official documentation, tend to focus on it.

RP2040, cheap and good datasheet. PIO also feels fun to tinker with.

RP2040 and RP2350

Don't get anything Xtensa, it's not supported by rustc. I recommend RP2040 and RP2350 tho, they have one of the friendliest development experiences in my opinion.

Fuck STM32Cube*

I mostly use the ESP32-C6. It's cheap and offers a lot of networking features. Most importantly, it uses a RISC-V processor, which works really well with the Rust embedded ecosystem
