Raspberry Pi 3 B Power Supply Pins

The 5v power pins are connected directly to the pi s power input and will capably provide the full current of your mains adaptor less that used by the pi itself. The final revision of our third generation single board computer. 1 4ghz 64 bit quad core processor dual band wireless lan bluetooth 4 2 ble faster ethernet and power over ethernet support with separate poe hat.

Raspberry pi 3 b power supply pins. Raspberry pi 3 model b. For raspberry pi 0 3 we recommend our 2 5a micro usb supply. This power supply can power the raspberry pi 3 b and other usb accessories such as most portable hard drives without requiring an external powered usb hub. This gpio pinout is an interactive reference to the raspberry pi gpio pins and a guide to the raspberry pi s gpio interfaces.

For raspberry pi 4 we recommend our 3a usb c supply. The power requirements of the raspberry pi increase as you make use of the various interfaces on the raspberry pi. The recommended amount is between 700ma for a raspberry pi model a and up to 2 5a for a raspberry pi 3 model b see power supply requirements in the magpi issue 56 page 39. Unlike the original raspberry pi model b the raspberry pi 2 model b cannot be back powered via the usb ports or at least can t be booted in this fashion.

Pinout also includes dozens of pinouts for raspberry pi add on boards hats and phats. The pi 3 has a recommended power supply of 5 1v at 2 5a which covers most situations. 25mm x 25mm brushless fan for processor cooling. It allows the raspberry pi to be powered via a power enabled ethernet network.

37 57v dc class 2 device. The gpio pins can draw 50ma safely distributed across all the pins. With a decent power supply such as the official 3a adapter on the pi 4 you can expect to pull about 1a to 2a. The raspberry pi poe hat is an add on board for the raspberry pi 4 model b and the raspberry pi 3 model b.

Earlier models demanded a lower draw of 5v at 1a but in practice greater amperage is usually preferable. The raspberry pi boards typically draw much lower amounts between 200 and 500ma. An individual gpio pin can only safely draw 16ma. Here are 10 ways to power a raspberry pi.

Raspberry pi 3 model b b plus with 1 4ghz 64 bit quad core armv8 cpu bcm2837b0 1 gb lpddr2 sdram. Mode 1 micro usb port 5v 2a the first recommended and easiest way to power the raspberry pi is via the micro usb port on the side of the unit. The raspberry pi gpio pinout guide. If you love pinout please help me fund new features and improvements.

For low power projects you can reduce the amperage quite a bit before it affects performance or stability.
