I need 4 UARTs, to use board as controller for home automatization: 1 - ZeegBee, 1 - GSM, 1 - RS485, 1 - M-bus. But in documentation, there are only 2 gpio uarts enabled for user. I wouldn't like to use external usb converters, this interfaces should be located on my expansion board, connected to the rock64 by GPIOs. Is there any solutions to solve my problem?
