Serial ports:

UART is required for communication with the driver board (stepper motors, ir_link, laser...), also it is useful for serial console (debugging) of the router board
I2C is necessary because there is communication with SFP modules
SPI is not that important, but it is good to have on some kind of expansion connector for some further upgrades.

Due to two SFP ports on the board, I2C multiplexing is required.
