Im working on a project with some servo motors, a hc-05 bluetooth module and an arduino nano. for some reason the arduino has started outputting around double the voltage on the 3.3V (6.7V measured) and 5V (9.5V measured) pin. this has damaged the bluetooth module. Other than the output voltage the …

Arduino voltage on 5V and 3.3V pins have doubled
