Actual behavior (suspected bug)
Not powering up. Before malfunction was functioning OK - running the chatGPT assistant for Home Assistant for >1 month. Today I noticed:
- Blank screen
- No green LED
- V USB = 5V, I USB = 0,05-0,12A
- Yellow Mute MIC LED can be switched on/off with its button
- Device not seen by PC
- Tried 3 different USB cables
- Tried powering via dock
- Tried BOOT + Reset buttons
- MCU_VDD test pad = 0,05V
- Other voltages seem OK
- No visible damage
As I understand, either the DC-DC converter or the MCU is kaput. I searched for warranty claim options, with no luck.
Error logs or terminal output
Steps to reproduce the behavior
- Apply USB power to the unit or to the dock
