Which GPIO pin on a Raspberry Pi is typically used to provide 3.3V power?
APin 5
BPin 6
CPin 1
DPin 9
Step-by-Step Solution
Solution:

  1. Step 1: Identify power pins on Raspberry Pi GPIO

    Pin 1 on the GPIO header provides 3.3V power output.

  2. Step 2: Verify other pins

    Pin 5 is GPIO, Pin 6 and 9 are ground pins, not power.

  3. Final Answer:

    Pin 1 -> Option C

  4. Quick Check:

    3.3V power pin = Pin 1 [OK]
Quick Trick: Pin 1 always gives 3.3V power on GPIO header [OK]
Common Mistakes:
  • Confusing ground pins with power
  • Choosing GPIO pins as power
  • Not knowing pin numbering
