Also SPI will be available as IO. In the time until the real release we will give you more and more details about it. We really encourage you to go into the myPLC configurator and configure what typically IO setup you are looking for. If there is some special IO missing … please use the “Custom requests” Box to tell us what you need.
I have seen also your email and I can tell you also that there will also be internal FLASH and FRAM connected to the processor.
