#Ground
The Ground pins ona the Raspberry Pi are all electrically connected, so it doesn't matter
The Ground pins on the Raspberry Pi are all electrically connected, so it doesn't matter
which one you use if you're wiring up a voltage supply.
Generally the one that's most convinient or closest to the rest of your connections is tidier
and easier, or alternatively the one closes to the supply pin that you use.
It's a good idea to use Physical Pin 17 for 3v3 and Physical Pin 25 for ground when using
the [SPI](/pinout/spi) connections, for example, as these are right next to the important pins for SPI0.
