Raspberry Pi 3 Model B Fan Pins

Full details are available here.

Raspberry pi 3 model b fan pins. This raspberry pi 3 pin fan is made of top quality aluminum alloy base and one fan with 5v 0 2a and could use together with motherboard with size. Prior to the pi 1 model b 2014 boards comprised a shorter 26 pin header. External circuitry may draw up to a total of 50ma max current from the 3 3v out pins. This is just a little video i put together to help pi starters get their hardware running.

Maximum 16ma per io pin sink or source with the total current from all pins not exceeding 51ma true for model b so presumably true for model b but not confirmed as full schematic not yet available. Connect the fan s red wire to gpio pin 4 5v and the black wire to gpio pin 6 ground. See a detailed explanation here. How to install raspberry pi fan for raspberry pi 2 and 3 model b.

Pins 1 2 39 40 are also labeled below j8 pinout 40 pin header. A 40 pin gpio header is found on all current raspberry pi boards unpopulated on pi zero and pi zero w. Rev 1 pi alternate gpio bcm numbers for the original 26 pin model a and b pi. Physical or board correspond to the pin s physical location on the header.

2 5 1 2 2 5cm ultimate slim and could use directly by backside adhesive tape this raspberry pi fan set meets the raspberry pi 3 and 4 long running working and overheating problem solution request. These are the small numbers next to the header e g. The raspberry pi 3 model b board contains a single 40 pin expansion header labeled as j8 providing access to 28 gpio pins. Raspberry pi resources raspberry pi developers our resources for other geeks designers and engineers.

Any of the gpio pins can be designated in software as an input or output pin and used for a wide range of purposes. If you d like your fan to only run when needed based on pi temperature check out our raspberry pi fan controller guide. Cooling your raspberry pi keep performance constant and drops temperature significantly. All io pins are 3 3v not 1 8v.

The fan should receive power automatically when the pi is booted. Pins are not 5v tolerant. Model b io pins pi hardware raspberry pi 1 model b model b io pins 3 3v output. Raspberry pi projects.
