I just saw these very well priced STM32H743VIT6 dev boards from the manufacturer that I usually buy me STM32F407VIT6 boards from
https://www.aliexpress.com/item/4000300 ... be362160f4

STM32H7 is a bit of an over kill for anything that I build but it may interest others.

Looks like new H7 variants of the MCUDev DevEBox.

This is the similar F4Vxxx version:

I made a board def for it.

I haven’t worked with H7’s before. If there are other H7 boards running MicroPython, should be pretty easy to make a board def for it. Just need to know which pins they map to the peripherals. If you are unable to get the schematics pdf from the seller, let me know and I’ll see if I can find it on Taobao. It’s often low res jpgs on AliExpress but you can find decent documentation on Baidu links on Taobao pages.

I do believe OpenMV are running MP on this exact MCU see https://openmv.io/products/openmv-cam-h7

I haven't ever play with a H7 but did have a little play with a M7 and found it had so many features for a beginner for me it was much easier to stick to a M4 and the M4 has always done anything that I have needed.

I have this board also and I would like to run micro python on it ?

Any way to do it ?

i have the official manufacturer pinout but I am not abble to deal with code...

If anyone could help

Here the file for pinout :

They might be a problem because My computer seems to do nothing when I connect this card.

Could I flash a program directly through Usb with my computer or did i need anything more ?

Here the official https://item.taobao.com/item.htm?spm=a1 ... 1083694791

Best Regard

mcauser, could you help me to upgrade your code for this board ?

I don't know how to manage the board def for micropython for the H743Vit6 board ?

Best and thanks !

Anyone could help ?

I'll take a look

@zaord this should get you started:

I don't have one of these boards, so I haven't tested it, but it's similar to the F4XX boards by MCUDev.
