Hi, I am trying to power a small pump using my raspberry pi 2b. If i connect it directly to the 3.3v output it works. However, when i connect it with an gpio output it doesn't... I am guessing the pump requires too much current from the gpio pin? Is there a sollution where i can still use a gpio to control the pump? I have looked for relays, but cant find any that not designed for higher voltages like 230V. Any ideas?
