The voltage seems fine. But the black square gets burning hot quickly. Does this mean the teensy is fried?

Thank you for your reply, both issues are with the same board. I used a solder rosin flux paste with the solder to solder the teensy, does this create a corrosive solder flux?

Hi! I just bought a new teensy 4.1 and when I plug it in, the teensy flashes rapidly 4 times, pauses for 4 seconds, and repeats. Does this mean something is wrong with the teensy? I am current unable to connect the teensy to arduino.

Hi! I have a teensy 4.1 and when I turn it on, the large black square at the center of the teensy gets very hot. Is this normal? I'm afraid of frying the teensy. Thank you.
