In the past, I had no trouble getting my first Pi Zero-W board to boot.
Something seems to have happened, such that with:
- three different boards (two newly purchased, one old that I think was blown out in an electrical storm)
- three different micro-USB cords (no particular provenance, but they successfully charge other electronics)
- different USB power supplies (an iPad charger, a MacBook Pro, a generic 5W USB charger)
- nothing plugged into or soldered on the boards yet (no GPIO, etc.)
I am almost never getting any of the boards to even light up their LEDs.
Is there something I should look into that might be causing such widespread failure?
