What to do if Thumb 2 only has flashing green light after powering up?

Thumb series requires a stable 5V or USB power supply.

Please check the applied power supply for the Thumb 2.

For a power supply from FC, please use a multimeter to measure and check the powering voltage for confirmation.

For an external USB power supply, please use a USB-A to USB-C cable with a regular phone charger or power bank to try powering on Thumb 2 camera again, as it is possible for a computer or a laptop to cut power for the camera.

If the issue remains, please send an email to run@runcam.com. For faster help, please provide us with photos/video demonstrating the issue.
