During rebuild of my prototype I need to shut power down and up. After this the Core doesn’t wake up !
Nothing changed on the power supply (5.6V DC on VIN).
Now I’m measuring 5,25 Vdc on the 3.3 V pin.
Does this mean that the all Core is dead ? Nothing burns.
Could it still be used without the power regulator and power with a 3.3 V power supply ?
