Raspberry Pi 3 B Power Pins

Pi hardware raspberry pi 1 model b model b io pins note that we are not currently sure if the new pin 27 40 pwm1 gpclk1 and gpclk2 peripheral pin functions will be made accessible under raspbian and if so which pins they will be assigned to hence the duplicated pins shown with these functions.

Raspberry pi 3 b power pins. The gpio pins can draw 50ma safely distributed across all the pins. The pi 3 has a recommended power supply of 5 1v at 2 5a which covers most situations. Usage depends on what you re doing with the pi. Some are very stringent in their required input.

Pinout also includes dozens of pinouts for raspberry pi add on boards hats and phats. 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. For raspberry pi 4 we recommend our 3a usb c supply. If you don t mix the 5v signal with the 3 3v signals everything should be alright.

For example the latest raspberry pi recommends 5v 2a as a minimum for stability but some are more flexible the arduino can accept a range of voltage inputs 6 20v and regulates this to desired level internally on board. With a decent power supply such as the official 3a adapter on the pi 4 you can expect to pull about 1a to 2a. In this case no problem. 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 0 3 we recommend our 2 5a micro usb supply. Sometimes you ll find sensors that are powered with 5v but all the communication pins are running with 3 3v. You can use the 5v power pin from the raspberry pi to power the component and then use any 3 3v gpio for the communication. Raspberry pi 2 raspberry pi 1 raspberry pi zero raspberry pi 2 b.

Raspberry pi platform is most used after adruino. 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. Intel galileo intel edison esp32 arduino due. At modmypi we offer a range of different micro development boards which all require slightly different power sources.

If you love pinout please help me fund new features and improvements. The power requirements of the raspberry pi increase as you make use of the various interfaces on the raspberry pi. Earlier models demanded a lower draw of 5v at 1a but in practice greater amperage is usually preferable. The raspberry pi gpio pinout guide.

For low power projects you can reduce the amperage quite a bit before it affects performance or stability. Here are 10 ways to power a raspberry pi. The raspberry pi boards typically draw much lower amounts between 200 and 500ma.
