If you need servo control then look at the node-red-node-pi-gpiod node as this is a lot more accurate timing wise, and more suitable for driving servos

The advantage is that it also talk to GPIO on a Pi that is remote as long as it is running the daemon, and also sharing pins works more cleanly as contention is handled by the multiple connections.

good way to access GPIO when running Docker on a Pi as you can use the network connection to link out of
the container to the PiGPIO daemon running on the host.
The disadvantage is that you must setup and run the PiGPIO daemon first.
