WebA powerful feature of the Raspberry Pi is the row of GPIO (general-purpose input/output) pins along the top edge of the board. ... This is made easier with the use of internal pull … WebSep 18, 2024 · But since the IO pins can have an internal pull-down, the DIP switch can also be wired to connect to 3.3V supply. No resistor is needed, but it must be taken care that in no case the pin becomes an output, or if it does, it will push or pull the voltage to the same voltage where the DIP switch common is connected.

WebJun 15, 2014 · Pin 2 of the Raspberry Pi expansion header is connected directly to the USB power supply — it isn't controlled by the CPU. Do not try to connect the fan directly to a GPIO pin; not only do they not output the right voltage, but they can't source/sink enough current to run the fan either. http://www.d3noob.org/2024/10/pull-up-and-pull-down-resistors-and.html
