Doesn't the reference scheme have galvanic isolation between pi-zero and arduino (a cpc5001)?
If you build both on one board (like Andreas) you might skip the isolation, but if you power them from different sources it might be easier to use an isolated UART than an isolated USB connection.
Of course you could also completely skip isolation, even when using seperate power connections. But then the system will be less robust.
