I will be using a few MCU’s to create PLC Modules, so it makes sence to create a template – starting project for each MCU. The most obvious is STM32G491RE. This template contains MCU, CAN, RS485, Crystal, SWD, Leds, FRAM and PSU condenced as tight as possible towards one side.
The template might change, but the idea is to get a flying start on new modules. As for FRAM and RS485 – if I don’t use them it cost me nothing to not assemble them!
