I want to start using the GPIO pins but I am worried about short circuits or using too much amperage and frying my raspi. What are the Min/Max Voltage and Current values rasppi can handle? What is the typical voltage and current? How sensitive is raspi to short circuits and things like that?
I have seen boards that are designed to 'protect' your raspi:
I don't really want to 'extend' the usefulness of my raspi I just want to protect it from getting fried by my GPIO pins. I'm intending on making a buffer circuit that will prevent my raspi from getting damaged from experimenting with the GPIO pins.
