Which STM32H5 evaluation kit supports 1.2V gpio?

Hey, I am looking for a STM32H5 evaluation kit or any other evaluation kit that can support my peripheral that is controlled by a 1.2V GPIO. Pls recommend an evaluation kit that can support the GPIO voltage rail configuration to change the voltage rail to 1.2V. Thanks.

Hi,

seems some pins can work at this voltage, but not the whole cpu: on H523..H562+563

How many pins you need at 1.2 V ?

Hello,

Thanks for your quick response, I will only need 2. Are you aware of any EVK that support such GPIOs?

Hi,

yes, i have the nucleo-H563 , there you can separate the vddio2 pin 121 and then supply it ...yourself: at 1.2V ...

...but be aware: pins at 1.xx V are not very fast , see ds H563 :
