I was actually planning to run it on F103 as I already have couple of them laying around. And I also wanted to try it in Rust mostly to get some experience with it. I was initially thinking about something that is already bluetooth enabled like ESP32 or CC2640R2 (I have development boards for both of these) but the design suddenly gets exponentially more complex if you want to get it right. Also, neither has a package that I can easily solder. I know it is just aesthetics, but I really like a clean board.
