Yesterday I got my reprap.me sanguinololu 1.3b - soldered the connectors, powered it up using a 1A 12V power supply(no steppers or stepper controllers attached), uploaded the firmware and made sure the thing communicates with Octoprint. All good.
However, I then left the board powered up for the night. This morning the IC1 was very, and I mean VERY hot on the board. Everything was still nice and functional but I powered it down just to be safe. Checked the power supply voltage, it's 14V without load. Could the extra 2V cause the 5V reg to grow hot?
