| May 22, 2020 at 15:32 | comment | added | PMF | @InigoEC: Sure. The power supply that provides the 5V has a voltage regulator that ensures the 5V remain 5V, regardless of how much power is drawn - up to a certain limit, which for the default Raspi power supply is 3 Amperes, which is a lot for just simple sensors. If it's just simple temperature or similar sensors, you could probably connect hundreds, till you overload it. | |

| May 22, 2020 at 10:01 | comment | added | Inigo EC | @Milliways but in that case I would have 2 sensors sharing 5v, would the sensors still be working as expected? | |
| May 22, 2020 at 10:00 | comment | added | joan | @Milliways the 50 mA limit applies to the GPIO bank circuitry, nothing to do with the 3V3 power rail limit. | |
| May 22, 2020 at 9:58 | comment | added | Milliways | @InigoEC solder 2 wires together | |
| May 22, 2020 at 9:56 | comment | added | Inigo EC | What would be the item I would need to buy in order to be able to supply power to the extra sensors? I can imagine somekind of small secondary board? | |
| May 22, 2020 at 9:54 | comment | added | Milliways | The 50mA limit is an urban myth. It may have been true for the original Pi which had a linear regulator. | |
