Hi Csaba,
Have you already ordered a board? Which one then?
According the datasheet (which is the same for both MCUs) the main difference is in available peripheral (GPIO ADC numbers) so the porting should not be a big issue.
I saw some chip boards on Aliexpress (e.g. https://www.aliexpress.com/item/33055327749.html?spm=a2g0o.productlist.0.0.31e118f3uHhzum&algo_pvid=2e4274c1-4e17-4ae4-98b0-3a4032525c42&algo_expid=2e4274c1-4e17-4ae4-98b0-3a4032525c42-5&btsid=41c9ce30-2da8-4f33-9a0f-a42f6c830e32&ws_ab_test=searchweb0_0,searchweb201602_9,searchweb201603_52) around 10eur/buck
There is also one with a sound driver on board [https://www.st.com/en/evaluation-tools/stm32f4discovery.html] from ST around 20eur/buck
Do you have any progress on this topic?
Best,
Mik
