I'm using the Nucleo F401RE board, and I was successfully reading analog signals from a 4-20mA signal generator for a project. I achieved this by connecting a 150-ohm resistor in series. However, the system suddenly stopped working, and upon investigation, I discovered that the LD3905 IC was overheating, and the microcontroller was also getting hot. Further examination revealed a short between the Analog pin PA1 (A1) and ground. I'm uncertain about the best course of action to get the board working again. Should I consider replacing the STM32F401 IC, or is there an alternative solution to resolve this issue?
