Description

Ultibo Platform Interface unit for Raspberry Pi 2

The RPi2 B has the Power LED connected to GPIO Pin 35 (Activity LED is now on GPIO Pin 47).

The RPi3 B has the Activity LED connected to the GPU, access is via a Virtual GPIO (Power LED is only accessible via the GPIO expander driver).

The RPi3 B+ has the Activity LED connected to GPIO Pin 29 (Power LED is only accessible via the GPIO expander driver).

The RPi Zero2W has the Activity LED connected to GPIO Pin 29.
