When power on-ed the raspberry pi, the red Led on the raspberry pi continuously start to blink while using raspberry pi charger. When i used another charger the red led got stable and board was getting heated up. Before this problem it was working smoothly and i had attached 2 hats on the raspberry pi (RS485 CAN HAT and L76X GPS HAT)and ethernet cable was also connected, and the 5G dongle was also connected to it via its USB port. when working with this all this problem encountered suddenly.is there any possible solution and what may be the reason for this?
- Is the RPI Power Supply (not charger) for your particular RPI or for another model? If the latter, you may not have enough power
- What is the rating of the RPI Power Supply which causes the blinking and what is the rating of the charger/power suppy where it does work?
- "...board was getting heated up" you may want to check the temperature of the CPU
- "I had attached 2 hats on the raspberry pi (RS485 CAN HAT and L76X GPS HAT)" Have you confirmed there are no PIN conflicts between the HATs. HAT's are not always designed to be stacked
- When the light is on steady, is everything working as expected?
- You may want to total up the amperage/watts needed for the RPI and all components to see if it exceeds the rating of the power supply.
