A WIO Terminal seems to have failed on me… blank screen, no LEDs lit, case warm. It had been running quite happily for several days, monitoring two I2C grove sensors (ATH20 and Miltichannel Gas) and reporting via WiFi + Mqtt; powered from a standard USB wall-wart.
Disconnect sensors: no change.
Different power supply: no change.
Plug Wio terminal into computer USB reports “Power surge on USB port.”
I assume something in the Wio’s USB-5V power has failed. Any ideas for how to investigate / fix please?
It’s a ‘TurboPower’ UK-AC (110-240V) USB supply, 5Vdc at 3A. I just checked that it works ok, first by charging a Huawei phone and then by powering a different Wio Terminal. Problem seems to be in the Wio Terminal itself.
Thank you for testing. This seems like an internal hardware issue. Possibly power circuit failure.
