Migrating from L4 to F4

What are the main points which I have to consider when migrating from STM32L4 to Stm32F4 apart from the connecting peripheral power management, Is there any main points which I have to consider when programming.

There are quite big differences between individual models in both lines - both families consisting of roughly 3 "subfamiilies", so you could perhaps be more specific in model numbers.

Read AN4821 and AN4616 .

RS485 not supported in F4

@Community member​  Right now I am using L476 but have to think about higher performance, so thought of going with the F4 series but not decided which family, more likely F469 or F479.

Unless you need some specific peripheral (the MIPI DSI display interface or SAI), the raw computing power of 'F469/479 is identical to 'F427/429/437/439/446 and only marginally better than that of 'F407/405/417/415.
