Can you post a picture of the fuse? v2.1 has been a while ago and I don’t particularly remember which type of fuse it uses.

In addition to replacing the fuse, I recommend you to remove power and measure resistance between VIN (i.e. 5V) to GND and also VCC to GND. VIN-GND should be at least 4 kilo ohm or above, VCC-GND should be at least 1 kilo ohm or above. If they look suspiciously low, some parts may have shorted and need to be replaced.

We are currently away till Sunday July 20. Orders placed during this time will be shipped on Monday July 21. Thank you for your understanding!
