Note that the GPIO pin names are markedly different from the RPi 3B.  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 primary or alternate names.  Source for GPIO designations was the Raspberry Pi 4 Model B datasheet.

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

Here is the proposed list of GPIO connections:

Note that the GPIO pin names are markedly different from the RPi 3B. Each pin on the RPi4 GPIO can be referred to in many ways: its physical pin number, the Broadcom I/O number, the Wiring Pi number or the primary or alternate names. Source for GPIO designations was the Raspberry Pi 4 Model B datasheet.
