I recently purchased the S3 Stick from M5Stack.
It's an ESP32 with:
- microphone and speaker
- wifi
- bluetooth
- screen
- two buttons
- IMU with six dimensions
all for under $35.
You can see a video of me using it to control a web based mini plane simulator https://x.com/alexpotato/status/2109782226841870352?s=20
Wild how cheap this kind of stuff has gotten.
