Serial-2-USB required?

[lars18th]

Hi,

In reference to the issue #16 about to replace the HID USB module with other alternatives, I have one question:

• As the Pi zero has UART ports in the GPIO pins, but the Pi3 has them too... why not interconnect them and remove the Serial-2-USB adapter?

Perhaps is an stupid question, but I really like to know why.
Please! :angel:

FYI, see this: https://scribles.net/setting-up-uart-serial-communication-between-raspberry-pis/

I comment this only because I'm not sure why this project doesn't interconnect directly both RPi's.
