RPiREF for Raspberry Pi is an easy and quick way of checking the Pin-out and GPIO references of Pi's P1, P5, P6 and J8 Headers.

This information is already available in a number of forms but having it available on your Android smartphone or tablet is useful when you are experimenting or discussing Pi ideas with friends.

This app provides reference information and covers :

Model A & B
- Pin numbering of the 26-pin GPIO Header P1
- Pin numbering of the P5 Header on Rev 2 boards
- P6 reset header
- 3.3V, 5V and ground pins
- Status LEDs
- Audio Jack (stereo audio)

Model B+
- Pin numbering of the 40-pin GPIO Header J8
- RUN reset header
- 3.3V, 5V and ground pins
- Status LEDs
- Audio Jack (stereo audio and composite video)

The app also contains some simple tips to identifying the different models.

The Zoom button on the GPIO header page allows you to set a zoom level so you can see the diagram in a size that suits your device and eye-sight. Just like the Model setting this is remembered between sessions.

This app is free and contains no adverts but does include a link to my website at the foot of some pages where you will find an article relevant to the screen you are looking at.

Don't guess. Check your connections with RPiREF!

If you rate this app please do so based on the app and this description. I don't claim it "connects to a Raspberry Pi" so please don't be too surprised if it doesn't :P

PERMISSIONS : This app does not ask for any unnecessary permissions. Just the way I like it!

All I Need! Wow! Thank you for a tight, clean, well conceived app. I wish all such apps were as well done. My respects.

Ergo Mu

Well done I found it simple to use

Matt Clairmont

Best reference app on the market! Thank you for a clean, permissions free, easy to use reference guide supporting all RPi variants!

Nigel Lester

Great for reference to GPIO ins and outs Maybe dev could add more useful info in a future update

Sameer Cooshna

Awesome ref fit the Pi Quick references at the top of my finger tips!

Mikael Sjösten

Riskware Use at own risk. Fraud.

Jon M

Even better The previous version with models A and B was awesome, and supremely useful for projects. Adding the B+ info to the app takes it to the next level. Excellent resource app. Thanks you for making it!

Alex Eames

Excellent reference always in my pocket I really liked the previous version, but this B+ update is even better.

William Wittman

Excellent reference to half!!!

Wayne Fowler

nice and handy

David Dennis

Good reference but missing some detail. I2C pins are not labeled on P1. I was also looking for detail on the flex circuit connectors but there doesn't appear to be any.

Martin Dietrich

usefull but... The numbering is left-right instead of top-down as it is on all the connectors that I have. Not sure if there is a standard, but it is confusing.

Ted Mieske

Like to give this 5 stars, but you need to update the GPIO to rev. 2

Andy Anderson

Fluid and uncluttered. Very clean and concise. There's no point in me saying you could add this and that as the board is small so could be covered in about 20 sections! Looking forward to the updates, please stick with it.

Greg King

Useful little app Great help for pinouts on my 2 Pis. It would be useful to have a hybrid photo with pinouts super-imposed and also a tab for the physical dimensions and mounting hole locations.

A Google User

It would be just what I need If I could switch between the models of raspi

Marcus Silva

Verynice Suggestions: - Include pinouts for all connectors. Yes, even the RCA and the "cam" connector :) - Have links on each connector that take you to corresponing connectors. Eg: clicking GP01 on GPIO pinout takes you to GPIO pin on the IC. Or links you to wiki articles/data sheets. (I know nothing about programming but let me know if I can help out with some easy to implement ideas.) :)

Ryan Walmsley

Great! Very handy with the rev changes in the app

Gary Jackson

Very good Pi reference! This is great for referencing the Raspberry Pi, both the app and the website. Well thought out, excellent content and non-intrusive. Look forward to updates for the Pi 2. Great job Dev! Very useful.


Non intrusive great work Totally free do not need any permission. Good references for the Pi. Keep up with your great work

Keith Meilleur

Hardware manual This is a nice little picture manual that revolves around just the hardware.

Adam Cadman

Useful info but... It's a bit out of date. Where's the Pi 2 and the new Zero?

John Maffysdad

Simple Yet Perfect. Doesn't need permissions, no adds, yet one of the best visual aids to those of us who have a interest in the Raspberry Pi.

Vic Voonevet

A necessary resource for all Pi users.

Shaun Harding

Needs rotate Great app , very useful I have several PI'S inc PI2 and play around with circuits. Very useful on my tablet but really needs to rotate for future version please.

slawomir buchała

Great and simple

A Google User

It would be just what I need If I could switch between the models of raspi

James Hill

Great reference app 5 stars for the Raspberry Pi 3 B

Raghu Kumar CK

Good handy info..Thanks
