Where are the GPIO pins of the STM32 NUCLEO-U5A5ZJ-Q board?

Question

Hello everyone, I hope you're having a great day. I was planning on buying this STM32 NUCLEO-U5A5ZJ-Q Board but as I was reading the user manual for the board, I realized there were no GPIO connectors for the board but rather there were these "ST Morpho pin headers",

I was wondering where the GPIOs were but as I did some experimenting with STM32CubeMX I discovered that I can set the pins in the ST Morpho Pin Headers to GPIO input or Output. Does this mean I can use these headers as the GPIOs of the Nucleo board or are these meant for something else entirely? I'm sorry if this is a silly question but if anyone can help me clear this up I would be very grateful.

Hello @purushotham2608

Yes, each morpho pin header is mapped to one of the gpio, GND, BOOT0,.... pin

So, you can use these headers as gpios.

PS: you should in some cases take care of the SBs and connnectors as you can see on the User manual.

Best Regards.

Most of the pins on the Morpho and Arduino connectors can be used for any purpose supported by the MCU. Some pins may require modification of the Nucleo board (removal/insertion of SB's) to make them available for your purposes. Doing so requires study of the Nucleo's manual and schematics.

For simple/quick/easy/prototyping things I usually use the Arduino connector signals if possible, if only to avoid having to hunt down the pin headers to populate the Morpho connector sites.
