Act one: Bought 5 stepper motor drivers, installed 4 of them, testing, droped a screwdriver, it makes 12V go into 3V bus, 4 drivers dead.
Act two: Bought 3 new drivers, and one more on a seller's advice after explaining the odd number. Installed one, about to try it out, catch a loose wire when moving a hand, 12V into 3V bus, driver dead.
Act three: Added and tested an overvoltage protection on the 3V bus, proceeded.
Screw up once - it's an accident, screw up twice - it's a coincidence, never screw up thrice unless you're an idiot.
