Hi,
Argon device is not connecting via USB serial and not booting up. it is blinking all colors. I did check voltage at enable pin is 4.1, at 3v3 is at 3.3V.
Reset and mode buttons are not doing anything. This happened when I used ADC at Pin A5 to detect battery voltage. The max voltage ADC got was 2.9V only.
Is it damaged?
