Even if you feed the board with 3.3v from the st-link ? * The 5v or 3.3v dc-dc converters could be defective, you can usually find the same dc-dc converters on the sideboards * If the board draws more than 100mA in idle, it's probably broken

Use a multi-meter to check the continuity between drain and source. If your multi-meter beeps, the mosfet is shorted so you need to replace it

Use a multi-meter to check the continuity between drain and source. If your multi-meter beeps, the mosfet is shorted so you need to replace it
