PCB v3.0.0-rc1

⭐ General

Warning

This is an untested v3.0.0 release (therefore rc1)!

@mourix joined the project and made some awesome PCB improvements! Thank you so much! Since we run out of GPIO pins all ESPs besides ESP32-S2-mini and ESP32-S3-mini are no longer supported. They should still work but will not be able use new features.

I just ordered some PCBs for testing. After testing I will release new docs & firmware. Happy wake word. Have fun :)

🚀 New Features

• Speaker support
  • You need this amplifier
  • We decide to add support for 3013 & 2307. Yes there are cheap as f*** but sounds surprisingly well. They will be mounted from the back to safe space so you have to print a new case or drill a hole.
  • You can also add your own notebook speaker instead
• Microphone support
  • Use this if you want to use the LD2450 mmWave
  • Use this in any other case
• HLK-LD2450 support (#92)

🛠 Fixes

• Better airflow for the BME sensors

New Contributors

• @mourix made their first contribution in #153
