Seeeduino XIAO SAMD21 Breaks When Powered by 220v Source

  1. I used the code you wrote in your previous response that only used 4 LED’s.
  2. The strip I use is from Adafruit with the Neopixel uberguide linked in the description.
  3. That is very similar to the code I was about to write. I was going to test to see if I could use the I/O pin attached to the Neopixel strip to check the current draw after lighting one more pixel to see if the board could sense when all the lights in a strip were lit, negating the need to specify the number of pixels in a strip, but I never got to that step before I ran into this issue.

Can I ask what issues do you believe could be happening to my XIAO, I am curious on what other issues there could be so that I learn now to avoid them.
