Hello, today i was casually working with my xiao samd21, but once when I plugged it into my computer, it stopped working. The reset pins give no life too. Can somebody please help me?
If “reset twice quickly” doesn’t bring it back to life, then it’s probably a brick.
Search “XIAO brick” in the forum and you will see many posts.
There are several ways to revive it, depending on your skills and the tools you have available. For example, the following links may be helpful.
