{{Admon/caution|You can Destroy Your Raspberry Pi|The BCM2835 is directly connected to signals present the pins on the GPIO pin header connector. Therefore, when you connect to the GPIO pin header, you are directly attaching to the SOC, and an over-voltage or over-current condition can seriously and irreversibly damage or destroy the SOC and render the Raspberry Pi useless.}}

# Grounding a pin (which is may be expected to be an input ) when it is configured as a high output (3.3 volts, often written as 3v3), either through the GPIO configuration or the PinMux configuration. This will cause a large current flow, probably damaging the Raspberry Pi. Likewise, connecting a pint which is expected to be an input to 3v3 when it is configured as a low output (0v) will have a similar effect.
