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.

SpaceGambler Posted December 1, 2022 Posted December 1, 2022 My LED panel supplier is offering Flexible LED panels with FM6124 Non-EPWM chipset, will this still be OK?

darden78 Posted February 23, 2023 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
Content Provider lucky1 Posted February 23, 2023 Author Content Provider 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

And now i have everithing but the nucleo
Content Provider lucky1 Posted February 23, 2023 Author Content Provider 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
darden78 Posted February 23, 2023 Posted February 23, 2023 it seems to be the same board, it just changes the chip mounted on it
Content Provider lucky1 Posted February 23, 2023 Author Content Provider Posted February 23, 2023 If you compare closer there are also resistors on different positions
darden78 Posted February 24, 2023 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...

darden78 Posted March 18, 2023 Posted March 18, 2023 i'm here again to ask about the nucleo boards: can the NUCLEO-H7A3ZI-Q work with the pin2dmdhd firmware? because in this moment it seems to be the only one of the stm32h7 family in stock

Only H743 works when you say "h743" you mean ALL the h743? i've seen there are vit6 chips, zit6, vgt6, igt6, iit6, etc. i think they are surely different from each other but do they all work on pin2dmd hd system?

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.

darden78 Posted April 6, 2023 Posted April 6, 2023 nucleo or devebox are sold out everywhere and where they are in stock they have inhuman prices, i have a project in my mind but i don't know how to do it because i don't know how to project pcbs, is there someone who can draw pcbs who wants to help me? thank you
