This hack only works with the old, recalled version of the POE HAT. Okay, maybe the Pi isn’t exactly bricked, but the USB ports won’t work after this. With the power over ethernet (aka POE) HAT on your Pi, plug any USB device into the USB ports. What if you could get power and internet in just one cable? There’s a HAT for that! “Raspberry_Pi_2_Model_B_with_Sense_HAT” by Khairil Yusof is licensed under CC BY 4.0Īll these cords are so annoying. They sit on top of the Pi, like a hat sits on your head. HATs are modules that give the Pi extra functionality. Keeping your Pi connected to power while the polyfuse resets is a great way to overheat the components. Tripped polyfuses reset after a couple of days.

To make sure you’ve bricked the Pi for good, keep the Pi plugged in to the battery after your failed attempt to boot it up. The USB battery listed above supplies 7 volts, which is way too much for the Pi. When more than 5.25 volts of power is supplied, Ohm’s Law dictates that there will be a corresponding increase to the amount of current. Which is why you shouldn’t attempt to power your Pi by plugging into a laptop or desktop computer. If you supply less voltage than required, the Pi won’t power on.

The Pi is engineered to work at 5 volts, plus or minus 5% (4.75 - 5.25 volts). The polyfuse won’t protect the Pi from over voltage, unfortunately. The Raspberry Pi has a polyfuse to protect it against over current, which is caused by drawing too much power from the GPIO pins. If all has gone according to plan, the Pi won’t boot up. 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.
