| Reasons to get a Pi: GPIO support, software support, OS updates, free root & bootloader, more flexibility and customizability, extensive documentation and support, consistency, simplicity, more ports, battery optional. Used phones are good for tinkering, especially for "display with sensors and battery attached" usecases, but there are still plenty of downsides. And unfortunately Linux on phones is just not ready for primetime, last I checked. |

| I've never used one but android phones can use utilize USB GPIO devices which are very cheap |

| Your phone has GPIOs inside it, but you can't access them without at least root. |

| ▲ | randomblock1 3 hours ago | parent [-] | | Cool, didn't know that. But like are they physically accessible? I don't think you can use the USB port as GPIO. Maybe some unused pins on the SOC itself, but that means opening up the phone and probably removing the shielding/heatsink... | | |

| ▲ | cowlevel 2 hours ago | parent [-] | | Now that's a funny idea. But it's true! | | |
| ▲ | amelius an hour ago | parent [-] | | I think you can attach a keyboard to a phone over USB, and in theory it can provide both input and output (you can control the LEDs from the host computer). That would be a more convenient route, I suppose. |

| PI was a thing when it was much cheaper than X86. You can buy a much better speced mini PC nowadays |

| ▲ | graemep 2 hours ago | parent | prev [-] | | For the cost of a Pico or a Zero? Even some of the SBCs cost about £30. Where can I get a mini PC for that? | | |
