5V pins onboard, all measure 4.6V Also checked 3.3V they all measure 3.3V

Tried both 12V and 24V power input using a Lab digital DC power supply.

Tested with nothing else connected, just a board on the table connected to a power supply.

Bad board? Or am I missing something ?

I added a diode here for safety X1 )JQOK4)P{W4N(HMRV2VU You can short it. 4.7V becomes 5V

should i be doing this or 4.6V is acceptable for stuff like PINDA and BL-Touch?

thanks for the quick responses

我应该这样做还是PINDA和BL-Touch之类的东西接受4.6V？
