What version you mean? I've added diagrams pinout from models A and B rev 1.0; as I explain in this article and many other tutorials, all GPIO pins that can act as inputs or outputs work at 3.3V and if you add them more voltage can burn your Raspberry.
Toleo gani maana? Nimekuwa aliongeza pinout michoro kutoka mifano A na B rev 1.0; kama mimi kueleza katika makala hii na tutorials wengine wengi, vigingi GPIO yote ambayo unaweza kutenda kama kazi ya pembejeo au matokeo katika 3.3V na kama unaweza kuongeza yao voltage zaidi unaweza kuchoma rasiberi yako.
