Schematics missing #3

Open samveen opened 4 years ago

samveen commented 4 years ago

The repository is missing the schematics of the board. I am trying to understand how to attach an SPI flash memory chip to the F401 version of the board, but without the schematics, I am unable to figure out the details.

Hi, The schematic of F401 is here： https://github.com/WeActTC/MiniF4-STM32F4x1/tree/master/STM32F401CCU6-Black-Board/HDK And STMF401 V1.2 version has been discontinued because of piracy.

Ah. My mistake for not checking the HDK subfolder. Thank you.

On the topic of piracy, I have purchased a WeAct STM32F401 V2.0 from an AliExpress store called GreatIT, because I cannot find any WeAct official store on AliExpress. How can I verify if I have an original and not a pirated copy?

Also, is it possible to add a note on reason for the the change in the values of capacitors C3,C4,C5,C6 from (12pF, 12pF, 4.3pF, 4.3pF) to (8pF, 8pF, 1.5pF, 1.5pF) from V2.0 to V2.1?

thanks
