Hi there - the EZ-B v4, or any of the supported ARC hardware with hardware UART will support those servos for reading. As well as any supported hardware for Software Serial (i.e. IoTiny or Arduino) will support for writing.

So yes, both those servos are supported. Depends if you want to read servo feedback or not. I do recommend the EZ-Robot EZ-B v4 though, because it has the most features including audio and video.
