A serial console is useful for debugging but not required for Pi 3B/4B/5B, since
the factory configuration enables network access via DHCP. For CM4 and other
variants without factory configuration, serial console access is required for
initial setup.
> [!NOTE]
> On the Raspberry Pi 5B the serial console is on `ttyAMA10` (GPIO pins 8/10),

To connect via serial:
1. Connect a USB-to-TTL serial adapter (3.3V) to GPIO pins:
