RPi BCM2837 Pinout

Back to RPi_schematics_breakdown

Raspberry Pi 3 GPU/CPU partial pinout

This is 100% unofficial! It was made by AndrewS using the data from the (reduced) Compute Module 3 schematics. So it might contain errors... and it doesn't contain any of the LPDDR2 (RAM) connections.

Colouring key
pin connects to a ground line
pin connects to a power line
pin is connected to signal line/something else

The positions of the pads roughly match up with this X-ray image of a Raspberry Pi Model 3B (note how it's only the bottom edge of the SoC that has pins all the way across).
