It would be pretty cool if a person could use their favorite microcontroller on a module board and use the main board merely to interface with the buttons, LCD, etc..
Buttons
The STM32 monitors the buttons. When a button is pressed the STM32 generates an interrupt output to the module. The module can poll the STM32 for button status.
Other peripherals
We can probably have the STM32 simple echo byte-for-byte all the communication between the module microcontroller and the peripheral. The STM32 would simple act as a conduit.
