Node Esp Voltage To D4

Node Esp Voltage To D4. If these are used as general purpose gpio pins they should be in the default states to boot from flash: If the 3.3 voltage is actually 4.7v, then your 3.3v regulator has failed, and as the esp32's operating voltage is 3.3v, it may have also damaged the processor.

D0 (gpio16, only on some boards): If the 3.3 voltage is actually 4.7v, then your 3.3v regulator has failed, and as the esp32's operating voltage is 3.3v, it may have also damaged the processor. Measure the input voltage on a0.
