Instead we will be holding a double lesson with a 30 min lunch break from 10am-2pm on Oct 30. Maximum Load on IO pins Current/voltage limits This section is important to not damage your Pi Short version the IO pins can pass 12mA of current. In OUT mode that is supplied at 3.3V V = IR V/I = R 3.3/0.012 = R R = 275 Ohms What this means is the minimum resistance on a circuit using the IO pins is 275 Ohms. To be safe add 50 Ohms to that. The maximum voltage supplied to an IN IO pin should be 3.3 V Other limits... 3.3V output has a maximum current of 300 milliamps VBUS (Which only works with USB input) supplies USB ...
