I've been working on this for about a year, and learned a lot about various elements of electronics and product design. Let me know if you have any questions on how it's designed, built, tools used, launching a product during the MCU/IC shortage etc.
It's aimed at hydroponics, aquariums, swimming pools etc, but also serves as a demo of a (small so far!) production device programmed in Rust.
Very cool! I think I missed it, or maybe it's not on the page because it's not relevant to the audience, but what MCU are you using? Always curious to see what people pick.
Great question - and you're right about that page not including it due to the audience. It's an STM32L4. (L443 specifically). I went with it since it's a versatile, well-documented MCU aimed at low-power, non-RF uses. I almost had to delay launch due to a shortage, but I got lucky when F5ing Digikey before they went out of stock again! Using a QFP footprint, although may switch to QFN on a future revision to avoid bent pins, and solder bridges high on the pins.
A blog article I posted a few days ago on the website goes into some detail about Rust, with a focus on STM32.
