I am running my Pi with an Iphone charger( 5V ~1A). It was running quite well and no hangups or anything. I was mostly using ssh to use it.
Recently, I hooked up and ADC(MCP3202) to connect a sensor to the pi. I ran into a few hangups during the last few days. Are there any ways to determine the root cause of the problem?
The voltage of the PI is usually around 4.75-80.
