currently I'm trying to use the mentioned tower modules. In the schematic files of both modules I have seen that the TWR-SER module uses the elevator pins A43/44 as RX/TX source. The CPU module maps UART5 to this pins. But this interface is also used for the OSBDM stuff. So is it right that the TWR-SER module isn't usable with the TWR-K60F120M?
