Ryde GPIO Connections

RPi 4 GPIO pin out

• Note the Rpi4 (only) can be powered with 5v directly on to GPIO 2 and 4.

Proposed GPIO Connections for the Ryde Receiver

Each pin on the RPi4 GPIO can be referred to in 4 ways: its physical pin number, the Broadcom I/O number, the Wiring Pi number or the name.
