Connect mbed F401RE to ROS on Pi3?

I'm using the mbed ROS Serial package on an Nucleo F401RE

Question 1: How to make the physical connection? I assume I connect the Pi's TX/RX pins (physical pins 8/10) To the F401RE RX/TX pins at D0 and D1. This should work as both are 3.3 volt serial. I assume ROS_Serial defaults to using D0/D1 pins put there are several UARTS on the F401RE. I figure I need to connect the grounds also from the Pi to the F401RE

Question 2: Can I change this? Is it possible to get the mbed to use different pins or even a different kind of connection such as SPI or I2C?

I can't find this in the docs, but the code (here) seems to suggest it's not using serial pins right now, but USB.

Perhaps @Gary Servin can shed some light on this.
