- Has somebody experience with them?
- Can somebody say something about the “quality of their engineering”? I am currently getting into microelectronics and wanna learn by examples, but obviously I can’t say whether something is the equivalent of clean or spaghetti code


They’re mostly using off the shelf chinese esp modules. They look like very polished hobby projects.
I’m a little envious of someone making what they want and selling it to people who want to buy it.
So good learning examples?
a good learning example would be recreating his designs yourself in CAD and writing your own firmware, or rolling your own version of QMK or whatever its running
You mean the Seeed XIAO boards right? Because most what I saw of them they were using the RP2040 chip (which is not ESP under the hood…is it?)
RP2040 is another jellybean part, much of a muchness. I’ve got both on devboards in my parts box.
