Where are the schematics for NUCLEO-H743ZI2

Hello,

I have here two Nucleos with an H743 on it. If it is rev Y, it is the "old" 144pin Nucleo board with the break-off ST-link board on top. For this there is a schematics in appendix A of the user manual. But if it is rev V, it is NUCLEO-H743ZI2 , note the 2 at the end, with no break-off possibility and a different user manual. And this manual has no schematics included. A trouble start as I start my project. While the manual says PC9 = MCO2 is on CN8 pin4 and CN12 pin1, I see a signal only on CN8 pin4. No way to check what's going on without schematics.

Please ST folks can you provide this somewhere.

Thanks a lot

Martin

Could you share me "which user manual you rely on?"

Hi Sco,

yes, sure, here are the manuals I use:

For the "old" 144pin Nucleo I have UM1974, page footer says DocID028599 Rev 7 December 2017

For the NUCLEO-H743ZI2 I have UM2407, page footer says UM2407 Rev 2, June 2020, which I downloaded just yesterday. This is the one I desire schematics for.

I hope you can help.

Hello,

I bought one Nucleo-H743ZI2 board and found the two capacitors (C71 and C72) for X2 32.768KHz are not installed. May I know if I need to install them with 5.1pF if I want to use the X2? I went through the manual "UM2407 User manual for STM32H7 Nucleo-144 boards (MB1364)". But it seems not mention the two capacitors for the LSE clock. Thank you.32.768.PNG
