Ah so the docking board uses a raspberry Pi eh? You could probably implement the same using an esp32 (if u want wifi/Bluetooth) or even an stm32 chip, you can definitely find a good chip for under $5 each that can do what you need. That's another way to take your learning to the next level while reducing costs. Also not as difficult as it looks!
See my other comment. I wanted to learn rust, but by the end, once I knew it, I wouldn't have chosen rust for a prototype if I started again.
These prototypes are running on a raspberry pi, though I wouldn't want to put them into production like that.

Yeah, I can run it on an stm32, which is what I'd do for an early Kickstarter where I only have to make <100.
Since I only made two, it was easier just to keep it on the raspi for now.
