The description of RPiREF

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)

Pi 3, Pi 2, A+, B+ and Pi Zero
- 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 RaspberryPi-Spy.co.uk 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!
