And 3.3V from the GPIO pin happens to be enough to trigger the relay (even though it theoretically expects 5V on the signal pin). If you had some part that communicates with the Pi in the other direction and uses 5V level logic then you'd probably have to use a level shifter to avoid frying the Pi.<br /><br />Why is 5V exposed at all? I guess for things like this and also you could probably power the Pi through that pin instead of the micro USB port.Jacek Fedoryńskihttps://www.blogger.com/profile/11480276832274345787noreply@blogger.comtag:blogger.com,1999:blog-5743520447405866726.post-21827217366181993112013-01-04T06:36:06.988+01:002013-01-04T06:36:06.988+01:00I keep reading about warning of not using 5V equip...I keep reading about warning of not using 5V equipment with the Raspberry Pi, but then I get a bit confused when the GPIO pinouts have 3.3V and 5V. Did you encounter any issues around that?pgibhttps://www.blogger.com/profile/05270790121585351605noreply@blogger.com
