Power trip meets comment war
Why a Raspberry Pi shouldn't be powered through its GPIO pins
Turns out the real shock wasn’t the wiring — it was the comments calling foul
TLDR: The article warned that powering a Raspberry Pi through its header pins can bypass some built-in protection and raise the risk of damage. But the comments stole the show, with readers arguing the advice was overstated, technically sloppy, and way less dangerous than the author made it sound.
A simple warning about powering a Raspberry Pi — a tiny, cheap computer loved by hobbyists — through the wrong pins somehow turned into a full-on comment section cage match. The article’s main point was straightforward: yes, feeding power straight into the board’s pin header can work, but you may skip some built-in safety features meant to protect the device from bad power, sudden spikes, and other electrical nasties. In plain English: the author was saying, “Sure, you can do it, but maybe don’t if you like your little computer alive.”
The community, however, was not content to nod politely. Several readers immediately pounced, arguing the warning was exaggerated or just plain wrong. One commenter bluntly said it was “incorrect advice,” insisting those pins are specifically power pins and perfectly fine to use in many setups. Another went even deeper, nitpicking the article’s description of the fuse and saying it doesn’t actually “blow” forever — it more or less recovers with time. Translation: the comments were full of people yelling, “Respectfully, that’s not how any of this works.”
And because no internet debate is complete without a joke, one user swerved wildly into comedy by mocking the site itself with a 503 error gag, basically saying even a Raspberry Pi wired the “wrong” way should still be able to serve the page. There was also some side-eye about whether special battery connectors already exist for this exact purpose. So while the article tried to save makers from accidental fried boards, the crowd’s verdict was messier: good caution, shaky explanation, elite nerd bickering, excellent popcorn value.
Key Points
- •The article uses the Raspberry Pi 1 power-input schematic to explain how the board receives and conditions power.
- •It identifies the Micro USB connector as the normal power entry point and says the incoming 5V passes through a fuse.
- •The article says a transient voltage suppressor protects the board from sudden input-voltage spikes that a fuse may not stop quickly enough.
- •It explains that input capacitors smooth ripple from lower-quality power supplies and help buffer sudden current demand.
- •The article concludes that supplying 5V directly through the header bypasses the USB-input protection circuitry and therefore carries greater risk if the power source is faulty.
