Raspberry pi 4 fritzing3/12/2024 Plug the Pi in to the battery with a USB-A to micro USB cable. Let’s say you find a mysterious USB battery lying around somewhere. Since the PMIC isn’t user repairable, you can request a new Pi from your supplier. Shorting the 3v3 pin damages this PMIC chip irreparably. The reason this “hack” only works on the Pi 3 B+ is because this model has a new PMIC (Power Management Integrated Circuit). If your multimeter shows 0 volts on the 3v3 pin, congratulations on successfully bricking your Pi! Of course, if you’re the conscientious sort, you can verify that it won’t boot by plugging the power supply into the micro USB port and ensuring the green LED doesn’t turn on. Make sure that your hands are so shaky that the probe slips off BCM 18 and hits the 5v pin, letting out all the magic smoke. Place the prongs of your multimeter on 3v3 power pin and BCM pin 18.ĭon’t use alligator clips to keep your probe steady. Let’s say you have a button hooked up to your GPIO pins, but pressing the button does nothing and you can’t figure out why. Shorting the +3 Volt Pinįor this hack, you’ll need a Pi Model 3 B+ and a multimeter. Today I’ll show you three easy ways to turn a Raspberry Pi into a paperweight. I learned over the course of my first hardware project that, well, hardware is hard.
