What is the best way of adding a fourth serial port to the ShieldBuddy?

I have an application that needs simultaneous access to 4 serials sensors. The 3 cores available on the ShieldBuddy are enough as the fourth serial sensor is only needed to check a condition before switching over to the 3 remaining sensors that are currently connected to the 3 serial ports on the ShieldBuddy.

A device like this can be used "in theory" but I do not know how long this board needs to "switch" the ports as this needs to be done in < 100 ms.

Thanks in advance.

Thank you. I am glad to hear that this library works with the ShieldBuddy.
