Is there a plan for a NUCLEO-U5xx board with TFT-LCD support?

[Rodo]

Hi all,

I was looking at NUCLEO-U5A5 but I need support for TFT-LCD. TFT-LCD support is only available on the U599/U5A9 and better (see table below). There is also a NUCLEO-U575 but again no TFT-LCD support.

Is there a plan to make a NUCLEO-U5xx with TFT-LCD support? Thanks.

Hello,

As far as I know, there is no planned Nucleo 144 board based on STM32U5x7/9.

Please have a look to these discovery boards:

STM32U5G9J-DK1 (TFBGA - DSI screen I/F - mcu @1.8V)

STM32U5G9-LQFP144-DK2  (LQFP-144 - 24bits I/F screen)

Correct me if I'm wrong but the STM32U5A5 and STM32U5A9 have the same pinout (LQFP144), don't they? I could buy a NUCLEO-U5A5 and replace the STM32U5A5 for an STM32U5A9 (equivalent version) and have my own NUCLEO-U5A9*.

I'll just have to make a project in STM32cubeIDE based on my custom NUCLEO-U5A9*.

This is possible, right? Assuming my soldering skills are not in the toilet :-). 

(*) Not a supported STM board :)

Hello,

I think so, the pinout seems the same, and that's what I would have done myself.

But, we never tried, so I can't confirm 100%.

I just checked the gerbers and the NUCLEO-U575 and NUCLEO-U5A5 boards are the same. A missing xtal on the U575 vs U5A5 is no big deal but the NUCLEO-U575 is cheaper. Since I'm gonna throw away the MCU might as well get the cheaper one. Are any of these boards available without MCU? Thanks.

No, there is always an MCU on the board.

It's not practical to have a dedicated board for every single chip variant, with every possible combination of external features.

In general, the boards use the "largest" family member - so you can prove your design on that, just ignoring the "extras" which are not in your intended chip.
