The only functionality my board will need to support is digital IO, two RS485 ports and a single RS232 port, but they do not need to be on the first version of the design. We just need to see the board come alive and toggle some IO lines to verify th...

I assume that STM32F407 is more likely to be compatible with STM32F207 rather than say STM32F412ZG since their features are different. It would be nice if there were a single document/web page which has all the compatible mcu's in a single location.

According to wikipedia: The F4 is pin-to-pin compatible with the STM32 F2-seriesFrom: UM1974 User manual- STM32 Nucleo-144 boardsNUCLEO-F207ZG -> STM32F207ZGTI can check if these are pin compatible and then reference the Necleo board schematic for th...

I was originally looking at Nucleo boards. Unfortunately we had an outside vendor write code for the Olimex STM32 H407 with STM32F407ZGT LQFP 144. I didn't see a Nucleo board with that specific processor. I wonder if there is another processor repres...

Agree totally about the STM32Cube, but I am also looking for reference designs so I can get an idea of which components people are using voltage regulation, bypass caps, etc. This is my first board so I want to minimize risk. So if I can start off ju...

Need quickest path for minimal PCB which includes LQFP144 STM32F407GTx device. Looking for reference design or schematic with BOM. For now I am reading AN4488 Application note. I am using Orcad schematic and layout software. Thanks
