Hello,
I am trying to use concept board with ehs6. The system restarts by displaying URC: ^SBC: Undervoltage Warning. Should I need to connect to an external power source other than USB?
Hi,
Do you use both USB connectors for your USB source (black and red)? Some PC's have a weak USB supply which may lead into the Undervoltage Warning.
The recommended Supply voltage on USB ports should be between 4.75 and 5.25 volts.
Best regards,

Hello,
USB should be enough.
Doe it mean that it restarts each time you try to power it on or it is possible to start the module?
Is it a new board or it was working fine before? Have you changed anything since that?
Regards,
