Lack of stm32f405 chipset.

Post by sim222 » Tue May 18, 2021 5:55 am

Hi guys,

I am developing the board using micropython and today I have loaded the default DFU file into the chipset.
It means it's time to order the chipset to manufacture.
However, I can't find any supplier for it. All stocks are gone now.

What should I do?
Should I change the chipset having the micropython DFU file officially? Then, which chipset you guys recommend?
I don't have enough skill to modify with source code to make DFU file for any stm32 chipset.

PLZ, guide me..

If you look at the ports/stm32/boards directory of the MicroPython sources, you can see which boards with STM32 chips are supported:

https://github.com/micropython/micropyt ... m32/boards

There are many boards with different F4 chips as well as others from the L/H product lines. These usually have the same level of support minus the periphery specific to the pyboard. For some, USB support may not be fully mature.

And then there are of course the other supported MCU families, like SAMD, RP2040, ESP32, etc.
