I have a project running that requires a stepper (the 28BYJ) and I am providing 9v / 1A to the ULN 2003 board. Can I take a feed from that same 12v supply to the Vin pin on the Ardunio? Thanks for any advice, Geoff

The barrel jack is the 'safest' implementation and it doesn't take up any limited header space.
