Yes, i opend a dispute and the pcb are on their way back, they will change the chip on their costs. Will see what happens and if they will work at the end 👍 But it wasnt easy at all, took me now 2 weeks until they admitted the mistake. Link to comment Share on other sites More sharing options...

darden78 Posted February 23, 2023 Share Posted February 23, 2023 it seems the NUCLEO-H743ZI2 will be avaible again from august 2023. Is there another board or directly another way to have something could work on rene's shield for pin2dmd hd? i thought i can just buy the correct chip (avaible but not cheap) and solder it in a different nucleo model to obtain a working board, but i need to know if there is some nucleo model which can work using this mehetod. Can anyone help me? thank you Link to comment Share on other sites More sharing options...
Content Provider lucky1 Posted February 23, 2023 Author Content Provider Share Posted February 23, 2023 Why don´t you use the EVO board instead of the Nucleo ? Just tell pcbway that stm32h743vit6 is available here https://www.lcsc.com/product-detail/Microcontroller-Units-MCUs-MPUs-SOCs_STMicroelectronics-STM32H743VIT6_C114409.html Link to comment Share on other sites More sharing options...

And now i have everithing but the nucleo Link to comment Share on other sites More sharing options...
Content Provider lucky1 Posted February 23, 2023 Author Content Provider Share Posted February 23, 2023 The Nucleo base boards are the same for all variant. There are just some solder jumpers / resistors set differently. See pictures attached for comparison of H743 and F429 Link to comment Share on other sites More sharing options...
darden78 Posted February 23, 2023 Share Posted February 23, 2023 it seems to be the same board, it just changes the chip mounted on it Link to comment Share on other sites More sharing options...

darden78 Posted February 24, 2023 Share Posted February 24, 2023 i tryed to search but i didn't find them, i just need them to be same value and do same work for both the boards so i can try to change just the chip on my F429... Link to comment Share on other sites More sharing options...

The question was about the Nucleo, so I meant that the Nucleo H743 with my answer. On the Nucleo the ZIT6(LQFP144) is used and on the EVO the VIT6 (LQFP100). The HD firmware needs 1MB of RAM and 2MB of flash. The core is running at 400Mhz. You could also use other models like IIT6 (LQFP176),BIT6 (LQFP208) etc but you have to modify the layout of the Evo accordingly. Link to comment Share on other sites More sharing options...
