I am new to Raspberry Pi, and I read somewhere that the default current you can pull from GPIO pins is 8mA, but that it can be configured to go higher. I just got a Pi Zero W. How can I get the current on the GPIO pins to a higher level than 8mA? Thanks!

  • This feels like a misconception - can you provide a reference for the assertion that the pins can only provide 8mA? All other Pi models are configured to provide at least twice that, and I'd be very surprised if that figure was any different here. – goobering Mar 16 '17 at 14:08
  • This is especially confounding since you have already asked and received an answer about the current potential of the GPIO pins -- an answer which I think you will find hundreds of versions of online, all saying more or less the same thing. The current is not configurable, nor is it regulated so you must take care not to exceed a recommended maximum. Yet suddenly you refer to having "read somewhere" something which contradicts this. This question is nonsense. I smell an XY problem in the background. – goldilocks Mar 16 '17 at 15:42

  • I think the confusion is caused by some using the term GPIO and pin interchangeably. You can set the GPIO drive current (e.g. pigs). You don't have any control over the 3V3 and 5V rail pins though. – joan Mar 16 '17 at 17:52
  • Programmable gpio driver strength is an Allwinner SOC thing not used by the Pi. – PaulF8080 Mar 16 '17 at 18:55
