The magpi issue 98.
Raspberry pi power pinout.
Raspberry pi standard 40 pin gpio header fully backwards compatible with previous boards 2 micro hdmi ports up to 4kp60 supported.
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.
All raspberry pi models since the b can provide up to 500ma on the 3v3 pins thanks to a switching regulator.
Forget the world of work for a while and build a full sized arcade cabinet complete with clicky buttons joystick and even a coin machine to extort money from yourself.
All raspberry pi since the model b can provide quite a bit more up to 500ma to remain on the safe side thanks to a switching regulator.
Along with the 5v and 3 3v pins 8 ground pins are available.
Power and ground pins are what let your raspberry pi power components like leds and motors in your project.

The raspberry pi gpio pinout guide.
Read it now hackspace issue 35.
The 5v pins give direct access to the 5v supply coming from your mains adaptor less power than used by the raspberry pi.
What each pin does on pi 4 earlier models.
In some cases it may be possible to draw more but due to lack of documentation and testing on the actual limits 500ma is given as a rule of thumb.
There are two types of power output pin in the raspberry pi 4 3v3 and 5v.
The official case for raspberry pi 4.
All power out pins are given below.
Pinout also includes dozens of pinouts for raspberry pi add on boards hats and phats.
The 3v3 supply pin on the early raspberry pi had a maximum available current of about 50 ma.
The power input pin of the raspberry pi 4 is given below.
The power and ground pins are used to power external circuitry.
With a decent power supply such as the official 3a adapter on the pi 4 you can expect to pull about 1a to 2a.
Raspberry pi gpio pinout.
All raspberry pis with the standard 40 gpio pins will have two 5v pins and two 3 3v pins always in the same place.
This gpio pinout is an interactive reference to the raspberry pi gpio pins and a guide to the raspberry pi s gpio interfaces.
5v is directly connected to the usb port but 3v3 is connected to through the regulator which gives the stable 3 volts output.
The zero lipo aims to give you the most compact raspberry pi power supply possible.
Enough to power a couple of leds or a microprocessor but not much more.
