Hey folks,
So after getting one of these Wemos S3 Mini Pro, I had to install ESPHome!
This is a really cool board with lots of peripherals, a nice price and an interesting full-color silkscreen.
For those looking to do the same, here is a starting point that I’m using…
There are a few problems however:
- Initially I had it working with ESP-IDF, however I started having some weird compile issues, and didn’t spend too much time investigating.
- The matching
lolin_s3_minidoesn’t seem to be supported with Arduino framework. Just using a generic ESP32-S3 for now… (though I guess it’s missing PSRAM?) - It’s not using the IMU (QMI8658C), since I didn’t find an example of it working with esphome.
- Also not using the IR Led, though this would be easy to do.
