I am powering my Raspberry Pi 5 through the GPIO pins using a Buck Converter that provides a 5V/5A output. I connect the converter's +5V output to the 5V GPIO pin and the ground (GND) to the corresponding GND pin on the Pi.
For serial communication with another device, I am using GPIO pins 14 (Tx) and 15 (Rx), and I ensured that the Pi's GND is connected to the GND of the device I'm communicating with. Based on my understanding, the communication wiring seems correct.
Everything worked fine for a couple of days, but the Pi suddenly stopped working. Now, only the red LED blinks, and there’s no green LED activity. According to documentation, a blinking red LED indicates that the input voltage is below 4.6V.
Initially, I powered my Raspberry Pi 5 using the original 5V/3A adapter, and it worked perfectly. After switching to the Buck Converter, it worked fine for a few days but then suddenly crashed. This is my second Pi 5 that has stopped working for some reason.
With the previous Pi 5, a similar issue occurred. Initially, the red LED was blinking, but after some time, it turned solid red. Additionally, the PMIC (Power Management IC) chip overheated every time that Pi was powered on.
In this current Pi, while the red LED is blinking, the PMIC chip is not overheating so far. The connections used for both Pi's were identical.
What could be the issue and how to resolve it.
