I have many similar projects. By far, the hardest part for anything I actually want to share is user friendly wifi provisioning. The rest is easy, displays, devices and power supply. (I have 5 different HL-tech radars on boards with 3 different displays, one using LVGL).
I am using the app based Espressive app based provisioning now and it's the best of the lot but still flakey on the Risk V chips like much of the IDF/Arduino wrappers. It's a hard problem.
Most of it works pretty well with the Extensa core so I suggest sticking with those.

- mianos 3y agoI'll add it and give it a try. Thanks.
