Hello, i want to connect my own hardware to a I/O-Pin.=20 1) Is it correct, that gumstix (on all GPIO ?) outputs 3,3V level and = accepts only 3,3V levels ? So when i have 5V level for an input of the = gumstix, how i can connect them ? Is a resistor enough or do i need a = level translator ? 2) Is there any possibility to get 3,3V out of the gumstix from the on = board regulator ? How much mA can i draw ? Or can i only get the power = from the main power supply and use my own regulator ? Regards, Martin |
