IPC-CPUF407 can be extended with a CAN interface and a second RS-485 interface

The IPC-CPUF407 module includes a CAN controller in the STM32F407 processor, but is not equipped with a bus driver. The IPC-CAN485 expansion module offers this interface and can also add a second RS-485 interface. Both CAN and RS-485 are galvanically isolated, providing increased protection against interference, ground loops and overvoltage. More information about the module can be found here, support is also available in the open application firmware.
